Abstract (en)

[origin: WO2015032422A1] The present invention relates to an induction heating cooker (1) comprising a full-wave rectifier (7) rectifying the alternative signal, a filter inductance (2) and a filter capacitor (3) at the output of the full-wave rectifier (7), a parallel resonant circuit (8) having a resonant inductor (5) and a resonant capacitor (6) disposed in parallel, a power switching device (4) in parallel with a reverse-biased freewheeling diode (8), said device operating such that the resonant inductor (5) and the resonant capacitor (6) involve in energy exchange, the power switching device (4) being connected to a collector node (10) whereon a resonant voltage (Vce) is generated, the induction heating cooker (1 ) further comprising a control unit regulating the operation of the power switching device (4) and a drive circuit that drives the same.
