Abstract
A multi-unit induction heating apparatus for cooking applications comprises a plurality of inverter units for generating high frequency energy, each of the inverters having first and second input terminals, the first input terminals being coupled respectively through first circuits to a first terminal of a low frequency power source, the second input terminals being coupled together to a common circuit node which is connected through a second circuit to a second terminal of the power source. The apparatus further includes a like plurality of manually operated switches respectively connected in the first circuits and a like plurality of first high frequency noise rejection filters connected respectively in the first circuits. The second circuit includes a common, high frequency noise rejection filter.
