ABSTRACT:
A power control circuit for at least two ohmic loads includes power semiconductors, switching elements and a control unit for adjusting the power consumption of the loads. In order to comply with international standards to avoid disturbances in mains supply systems when higher loads are switched, a simple and cheap circuit is described which is also suitable for smaller domestic appliances such as light cookers, flat-irons, cooking vessels etc. A control unit controls a switchable power semiconductor unit which can pass current in two directions and connects one or both loads to the single power semiconductor unit via the switching elements in a variety of circuit configurations so as to adjust the power to the loads as required.
