INDUCTION HEATING APPARATUS WITH MEANS FOR DETECTING ZERO CROSSING POINT OF HIGH-FREQUENCY OSCILLATION TO DETERMINE TRIGGERING TIME |
摘要 |
Induction heating apparatus using gate-controlled switching devices includes a zero crossing point detector for detecting the occurrence of each zero crossing point of high frequency energization current, and a timing circuit which provides timing action in response to the detected zero crossing point. The timing action is controlled by a power control circuit which detects the level of energy delivered to a load within a range from the inherent turn-off time of the gate-controlled switching devices to a desired value. |
