    Abstract: Alternating current (AC) photovoltaic (PV) modules are described. In one example, an AC PV module includes a PV panel (100) having a top surface, a bottom surface, and a plurality of sides extending between the top surface and the bottom surface, a frame (104) adjacent the plurality of sides of the PV panel, a junction box (204) attached to the bottom surface of the PV panel, an inverter (214) adjacent the bottom surface of the PV panel, and at least one direct current (DC) conductor (206) extending from the junction box to the inverter. The DC conductor is prevented from contacting the frame and/or other grounded metal.

    Abstract: Soft switching power converters are described. In one example, a solar power converter includes an inverter input to receive a direct current (DC) power input and an output to provide an alternating current (AC) power output. The converter includes a first and a second power branch, and a controller. The first power branch includes a plurality of first switches and a first current sensor configured to generate a first current signal. The second power branch includes a plurality of second switches and a second current sensor configured to generate a second current signal. The controller is configured to control switching of the first and second plurality of switches to provide the AC power output based at least in part on the first and second current signals.
