Abstract (en)
[origin: EP0286044A2] The current supply circuit uses a current source (G) supplied from the mains voltage (Ua) which is coupled to either or both of two inductive cooking plate (P1,P2) via respective relays (A,B). These are operated via a microprocessor (M) at the gas transition points of the mains voltage to prevent moustic noise. Pref. the opening of one relay and the closing of the other relay are effected within an interval of 1.2 M5 on either side of the zero transition point for the mains voltage. Alternate switching supplies both plates with a respective power lever under control of the microprocessor (M).
