Abstract: Integrated power modules according to the present technology may include a printed circuit board characterized by a first surface and a second surface. The integrated power modules may include one or more surface-mounted components coupled with the first surface of the printed circuit board. The integrated power modules may include a heat-transfer substrate. The integrated power modules may include one or more gallium nitride transistors coupled between and soldered to each of the second surface of the printed circuit board and the heat-transfer substrate. The integrated power modules may include one or more spacers coupled between and soldered to each of the printed circuit board and the heat-transfer substrate.

Abstract: An energy storage system can include a battery, a power converter comprising a first plurality of switching devices coupled to the battery and a second plurality of switching devices coupled between the first plurality of switching devices and an AC power system, and control circuitry that determines whether the AC power system is a single/split phase system or a three phase system and operates the first and second pluralities of switching devices accordingly. The control circuitry can include a microcontroller and a plurality of voltage sensors each configured to monitor a magnitude and a phase of a voltage to allow the control circuitry to determine whether the AC power system is a single/split phase system or a three phase system and whether the AC power system is connected with a line to line or line to neutral fault condition.
