A semiconductor circuit suitable for normally-on switching elements or switching elements low in threshold voltage. A negative power supply is charged by a high-voltage power supply. A high-voltage switch controls the advisability of applying a voltage to a high-voltage terminal. With deducing the power supply to power switching elements, the high-voltage switch is turned off, and even in the case where the voltage of the controlling circuits of the power switching elements is reduced, the power supply capacitors for the controlling circuits are charged by the high-voltage terminal thereby to operate the controlling circuits. Further, a negative power source voltage generating circuit utilizes the energy charged to the capacitors from output terminals. A voltage terminal is inserted between the high-voltage terminal and a reference voltage terminal. The negative power source voltage generating circuit is interposed between the voltage terminal and a plurality of the output terminals.

A modulation control scheme for a series-connected dual active bridge (DAB) DC to DC converter in a maximum power point tracking charge controller used in a photovoltaic system controls operation of the converter in a forward direction power flow mode to control charging of a battery bank with electricity produced by the photovoltaic array. The modulation control scheme is also capable of operating the converter in a reverse direction power flow mode to control the flow of electricity from the battery bank to a DC load. The modulation control scheme divides the converter's operating range in each mode into five main cases of minimum root mean square (M-RMS) operating regions and seven main cases of full zero-voltage switching (F-ZVS) operating regions, as well as transition operating regions between adjacent main cases, based on applicable power level and value of voltage differential.
