Abstract
A current limiting impedance network for a dryer control in which a controlled conduction device, such as an SCR, is connected to shunt an AC motor to selectively prevent operation of the motor, in which a current limiting, power dissipating resistor is replaced by a lower value and lower power rating resistor and a capacitor connected in series with the resistor. The capacitor has a capacitive reactance of a value approximately twice the inductive reactance of the motor to provide substantially the same magnitude of circuit impedance as with the current limiting power resistor and cause operation of the circuit with a leading rather than a lagging current phase angle.
