Power Integrations, the leader in high-voltage integrated circuits (ICs) for energy-efficient power conversion, today announced a 900-volt gallium-nitride (GaN) extension to the company’s InnoSwitch3™ family of flyback switcher ICs. The new ICs, which feature the company’s proprietary PowiGaN™ technology, deliver up to 100 watts with better than 93 percent efficiency, eliminating the need for heat sinks and streamlining design of space-challenged applications. InnoSwitch3 designs also offer exceptional light-load efficiency making them ideal for providing auxiliary power in electric vehicles during low-power sleep modes. The AEC-Q100-qualified InnoSwitch3-AQ family is particularly suitable for EVs based on 400-volt bus systems where the 900-volt PowiGaN switch provides more power and increased design margin―required for 12-volt battery-replacement systems―with enhanced efficiency over silicon-based converters.

“The dominant bus voltage for electric vehicles is 400 volts,” stated Peter Vaughan, automotive business development director at Power Integrations. “EV manufacturers are optimizing their new generation of 400-volt systems and re-engineering various power stages in the vehicle, such as the on-board charger. The 900-volt PowiGaN switch is extremely beneficial because it easily accommodates inductive noise spikes, yet it can operate from as low as 30 VDC, enabling systems to meet functional safety active discharge requirements. The extra power delivered by our GaN technology matches the increasing power demands of EV manufacturers, moreover, efficiency in power conversion―even in auxiliary systems―is important for both range extension and thermal management.”

In the industrial space, extra power and increased efficiency are extremely advantageous in applications such as appliances, three-phase motors and auxiliary power supply units (PSUs) in servers. The new 900-volt parts are pin-for-pin compatible with existing 725-volt and 750-volt InnoSwitch3-EP parts and offer increased safety margin which is ideal for countries with unstable line voltages.

“Our ability to deliver GaN parts rated at up to 900 volts demonstrates the reliability and ruggedness of our PowiGaN technology,” stated Silvestro Fimiani, senior product marketing manager at Power Integrations.

The new 900-volt InnoSwitch3-EP and InnoSwitch3-AQ off-line CV/CC flyback switcher ICs employ synchronous rectification, a valley switching discontinuous conduction mode (DCM) and continuous conduction mode (CCM) flyback controller. FluxLink™ communication technology enables the IC package to bridge the isolation barrier, optimizing efficiency and eliminating the need for optocouplers. PowiGaN technology enables InnoSwitch3-EP ICs to deliver up to 100 watts (230 volts alternating current [VAC] plus or minus 15 percent) without heat sinks. InnoSwitch3-EP devices incorporate multiple protection features including line over- and under-voltage protection, output over-voltage and over-current limiting, and over-temperature shutdown. Devices are available with standard and peak power delivery options. Automotive InnoSwitch3-AQ devices can also deliver 100 watts from a 400-volt bus and provide performance and protection features similar to those of the popular 1700-volt silicon-carbide InnoSwitch3-AQ ICs currently used in 800-volt EV systems.

Availability & Resources

Pricing for the new 900-volt GaN InnoSwitch3-EP devices for industrial applications start at $2.00 for 10,000-unit quantities.

Polar Power Launches New Line of Mobile Electric Vehicle Chargers

Globenewswire | May 11, 2023

Polar Power Inc. a global provider of prime, backup and solar hybrid DC power solutions, announced it is now taking advance orders for its new line of mobile Combined Charging System (“CCS”) Electric Vehicle (“EV”) chargers, which are expected to be available before the end of the first quarter of 2024. Mobile EV chargers are used for emergency roadside service providing a fast-charging solution for EVs that have run out of charge before reaching a stationary charging facility. The goal is not to fully charge the vehicle but place a sufficient charge allowing the vehicle to proceed to the nearest charging station; this being analogous to the can of gasoline provided to stranded motorists. Polar is currently upgrading its mobile CHAdeMO EV chargers to the universal CCS standard to meet the larger market opportunity. Because of the supply chain shortages and long delivery of engines and electronics, Polar is taking orders for shipments starting in the first quarter of 2024. Since 2011 Polar has sold its CHAdeMO chargers to most of the major U.S. automakers for fast charging their EVs during field testing. The performance advantage Polar provided to mobile EV charging was a significant reduction in the charging system's size, weight, fuel consumption (for both the charger and vehicle transporting the charger), and system cost. Using the Polar system, a complete charging system can be deployed on the back of a small pickup truck relative to alternative solutions requiring a large trailer towed by a truck or tractor/trailer. The Polar mobile EV charger technology is DC based and is less than half the weight and size of an AC generator coupled to an AC to DC charger. The other alternate solution to an EV running out of power on the road is a flatbed truck to transport the vehicle to the nearest charging station. This is a cumbersome solution requiring a considerable time to load the EV, transport it, and unload it at the charging station. In aggregate, this can take hours and to exacerbate the situation, in many cities, there is a long wait for flatbed truck availability. Using a mobile EV charger allows a small van or pickup truck to perform a 15-to-30-minute charge (about the same time required to only load the vehicle on to the flatbed truck) allowing the motorist to drive to a charging station, which is a substantially more elegant and cost-effective solution. In fact, the Polar EV chargers are small enough to be installed on tow trucks / wreckers or on a small pickup or van. Polar expects this will substantially accelerate the establishments of fleets to serve the fast-growing EV market. The first sizes to ship will be 15 kW and 30 kW using either propane, natural gas, or diesel. Polar's next generation of DC alternators, its 9000 series, is in test with 50 kW charging output. These chargers are expected to be available in the second quarter of 2024. Mr. Arthur D. Sams, CEO of the Company, comments, "There is a large number of gas stations in our cities and highways with short lines where it takes only minutes to refuel yet there are still a substantial number of drivers that run out of fuel," said Polar Power CEO Arthur Sams. "I am intimately familiar with the challenges as an EV owner myself for the past 8 years and I know that keeping a charge in your vehicle requires an extra effort. There have been many times that I arrived at the charging station with less than 5 miles of charge remaining in the vehicle and I expect this is a familiar comment from many EV owners". "One factor causing EVs to run out of charge is commonly referred to as phantom discharge or vampire drain; EV owners can experience continued battery discharge while the vehicle is parked. My EV loses up to 10 miles a day while my car is parked at the airport, so I must make sure there is sufficient charge to manage the time away from the vehicle and the charge needed to get home. The factors causing phantom discharge vary from EV to EV, including preconditioning and temperature regulation of the battery and cabin interior, security cameras, charging the onboard 12 Vdc battery, and miscellaneous apps. As soon as I figure out the setting to reduce my phantom discharges, a software update comes along and seems to switch them on again. In addition to the EV owners’ needs for mobile charging there are the needs of EV manufacturers, transportation logistics, and dealer sales lots. When the automotive manufacturing plant ships an EV there can be problems with dead batteries due to long storage and transportation time, mobile chargers are needed at the docks, storage yards, and the dealerships. Fleet vehicle operators need mobile chargers to maintain and service their fleet. Mr. Sams concluded, "Many EV owners are burdened with range anxiety, and we can provide a cost-effective and easily accessible solution to give owners greater comfort through emergency on-road charging solutions using our power technology platform. The incumbent solution frequently leads to bad experiences for EV owners who have faced very long waits for a flatbed truck to haul their EV to a charging station, keeping in mind that most EVs are not even towable with standard tow trucks. Overall, we see this as a substantial market opportunity for us by providing the enabling technology to solve this real-world problem that will only become more prevalent with the proliferation of EVs. We believe supplying each city in the USA with just one mobile EV charger represents a huge market potential." About Polar Power, Inc. Gardena, California-based Polar Power, Inc. designs, manufactures, and sells direct current, or DC, power systems, lithium battery powered hybrid solar systems for applications in the telecommunications market and, in other markets, including military, electric vehicle charging, cogeneration, distributed power, and uninterruptable power supply.
