摘要：A pulse width modulated D. C. to A. C. inverter circuit includes a first set of MOSFETS operated at a line frequency for transmitting high frequency clock pulses to a second set of MOSFETS for outputting a D. C. signal derived from a D. C. source. The inverter is part of an uninterruptable power supply and is operated upon the failure of the line A. C. to supply A. C. signals to a load. The high frequency clock signals are modulated on the A. C. output of the inverter. Two separate and distinct power switching channels are provided with each channel supplying one half of the sine wave outputted by the inverter.
