Abstract
A circuit for controlling power consumption of a load, by controlling the flow of current thereto, utilizes at least one parallel combination of non-linear resistance elements, such as a varistor and the like, and a gateable semiconductor switching device, such as a triac and the like, to substantially reduce or prevent current flow when the semiconductor switching device is gated to an 'off' condition and to enable normal current flow to a load when the semiconductor switching device is gated to an 'on' condition. Embodiments of the power circuits for control of magnetron power, in a microwave oven, are illustrated.
