ABSTRACT:
A voltage converter apparatus is provided to energize a first load and a second load from a power supply connected through an inverter and a coupling transformer, with the transformer having a first secondary winding energizing the first load with first voltage pulses having a variable width determined by the operational frequency of the inverter and having a second secondary winding energizing the second load with second voltage pulses having a variable width determined by a phase controlled switching apparatus responsive to one of the voltage and the current of the second voltage pulses.
