ABSTRACT:
A method and system for controlling a dual output power converter of the type having a pair of input terminals connectable to a source of rectified AC power of variable voltage amplitude, a boosting circuit including a secondary winding of a boost transformer operatively coupled in circuit with the pair of input terminals for providing a boosted voltage onto a DC power bus, and a full-bridge inverter including at least one controllable switching device serially connected in each leg of the inverter. The inverter has an input connected to the DC bus and a pair of output terminals connected to respective ends of a primary winding of an output transformer, at least one of the pair of output terminals being connected in circuit with the primary winding of the boost transformer. The control system compares signals representative of the magnitude of the AC power voltage to signals representative of the DC bus voltage and varies the inverter frequency of operation in a manner to adjust the magnitude of the DC bus voltage to establish a preselected ratio of DC bus voltage to AC power voltage.
