Abstract
A voltage converter circuit uses a silicon-controlled rectifier for converting input voltage to selected levels of output voltage. The silicon-controlled rectifier is connected in a circuit including a capacitor which oscillates between charging and discharging to produce a resulting waveform that is applied to a transformer for developing high positive and negative output voltages. Pulses are produced which are asynchronous with alternating line signal. Since the silicon-controlled rectifier operates on DC voltages, an electrolytic capacitor of high capacitance values can be connected between the silicon-controlled rectifier and AC or DC supply lines to substantially reduce noise signals conducted back into the supply line.
