ABSTRACT:
A power convertor wherein a piezoelectric ceramic transformer generates a voltage, a resulting current passes through a load and a comparative voltage generator to generate a comparative voltage. The comparative voltage is amplified and compared to a standard voltage to obtain a control voltage. The control voltage is regulated to provide base potentials of a power amplifier. As a result, variations in a variable resistor will change the comparative voltage to obtain different output currents as required.
