Abstract
A saturable reactor regulated power supply utilizes a power oscillator to convert line voltage to a higher frequency voltage. The high frequency voltage is passed through the gate windings of a saturable reactor to an output circuit including an output power transformer. A feedback circuit interconnected between the output circuit and control windings of the saturable reactor controls the control winding current in order to pulse modulate the voltage applied to the output circuit. The feedback circuit includes several resistors which are connected to cause a phantom control winding resistance R.sub.c * which is much greater than that of a control winding series resistor R.sub.1. The created phantom resistance R.sub.c * causes the control winding circuit time constant to be substantially less than that which would otherwise be provided by the series resistor R.sub.1 ; whereas, the resistor R.sub.1 determines the control winding power loss.
