Patent number: 6770857Abstract: An induction heating apparatus can heat aluminum pot etc. with pot vibration noise being suppressed. During a turn-on time of second switching device 57, an energy is accumulated at choke coil 54, and at the same time a resonant current with a shorter period than the turn-on time of second switching device 57 or a driving time of first switching device 55 is generated at heating coil 59, so that during turn-off of second switching device 57, i.e., during on-time of first switching device 55, the energy accumulated at choke coil 54 is transferred to second smoothing capacitor 62. And then the output power is supplied from smoothing capacitor 62 to heating coil 59, thereby reducing the pot vibration noise, which is caused by pulsating current of input voltage.Type: GrantFiled: February 27, 2003Date of Patent: August 3, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Izuo Hirota, Atsushi Fujita, Takahiro Miyauchi, Takeshi Kitaizumi, Yuji Fujii, Kouji Niiyama, Hideki Omori
