ABSTRACT:
There is disclosed herein a power control unti for controlling the voltage and power delivered to a single phase load, said control unit being preferably employed with loads whose impedance changes but slightly over the work cycle. The circuit utilizes a diode rectifier and a controlled rectifier connected in parallel therewith connected in series with capacitance and achieves transient-free and harmonic-free power control.
