<P>PROBLEM TO BE SOLVED: To provide a high-frequency heating inverter apparatus having a simple constitution, electrically balancing currents flowing in the switching elements, and surely preventing the switching elements from damages. <P>SOLUTION: The high-frequency heating inverter apparatus comprises a plurality of arms, bridge-connected and having the semiconductor switching elements, and current-balancing means connected between a common terminal and the switching means. The current-balancing means is formed by bending a U-shaped copper plate at a predetermined location and is provided with a first conductor inserted through one opening of a core and wound, and a second conductor inserted through the other opening of the core in a penetration state and carrying a current in the direction reverse to that of a current flowing in the first conductor. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
