ABSTRACT:
Circuit arrangement for producing an alternating output voltage from a d.c. input voltage employing two d.c. to a.c. voltage converters, i.e., inverter circuits, which are controlled by high frequency pulse width modulated signals so that one of the inverter circuits produces the positive half waves of the alternating output voltage and the other inverter circuit produces the negative half waves of the alternating output voltage. The outputs of the two voltage inverter circuits are connected in series across a common load and controlled electronic power switches are provided to short-circuit the output of the respective inverter circuit during the time period when it is not producing output energy.
