Title:
INDUCTION HEATING APPARATUS USING DUAL-FREQUENCY RESONANT INVERTER
Document Type and Number:
WIPO Patent Application WO/2016/167501
Kind Code:
A1
Abstract:
Disclosed is an induction heating apparatus using a dual-frequency resonant inverter. An aspect of the present embodiment provides a power supply device for supplying power to an inductive load (Lc) of an induction heating apparatus, the power supply device comprising: a generator for selectively outputting alternating current (AC) power having a first frequency or AC power having a second frequency; and a resonant circuit unit for configuring the inductive load (Lc) and a resonant circuit according to the frequency of the AC power output by the generator, wherein the first frequency is higher than the second frequency, and the resonant circuit unit operates as a series-parallel resonance circuit when the AC power having the first frequency is applied thereto and operates as a series resonance circuit when the AC power having the second frequency is applied thereto.
