is showcasing a GaN-based, dc-to-dc boost converter running at more than 99% efficiency. The company’s GaN-based power converters are designed with 600 Volt transistors and low loss power diodes, will come in industry-standard packages, and are designed for optimum high-frequency switching, lowest loss and highest efficiency.

The drive components (motor, two-stage 1-speed transmission) of the HyMotion are in the engine compartment of the car as are the hydrogen fuel cell stack; the cooling system; a tri-port converter that regulates the voltage between the electric motor, the fuel cell and the lithium-ion battery; and the turbo compressor.

In electronic devices, WBG semiconductors can eliminate up to 90% of the power losses that currently occur during AC-to-DC and DC-to-AC electricity conversion, and they can handle voltages more than 10 times higher than Si-based devices, greatly enhancing performance in high-power applications.

Les Goldman wants you to convert (your hybrid.) So he proposed at the California Air Resources Board ZEV workshop on Tuesday. Tuesday's workshop was not so different. They've been converting some cars back east, working out the kinks. Hybrid drivers in California could finally actually get their hybrid converted.

Half-bridge circuits are the centerpiece of many voltage converters. For example, the switching frequency can be improved by a factor of around 10 in comparison with conventional voltage converters. A folded chip layout enables the DC link capacitance to be tightly connected between the supply voltage and ground.

The projected number of charging ports will need to grow to an estimated 6,000 to 12,000 public ports (some 300 being DC fast chargers) and 18,000 to 26,000 residential ports, with most of those being L2-type charging ports. For instance, Marshall stated, it is not unusual for a 37.5
