摘要

部分串联谐振功率变换器，以前只用于DC-DC变换器，现在应用于感应加热。该电路采用半桥串联谐振电路，其箝位二极管将谐振电容的电压限制在零和电源电压之间。研究了三种类型的控制:恒定开关频率;恒关断电流;以及它们的组合。后者似乎是最好的。该电路仅适用于Q值较低且工件温度低于居里温度的负载。

A new induction heating circuit with clamped capacitor voltage suitable for heating to above Curie temperature

The partial series-resonant power converter, previously only used for DC-DC converters, is applied to induction heating. The circuit is a half-bridge, series-resonant circuit with clamping diodes that constrain the voltage of the resonant capacitors to values between zero and the supply voltage. Three types of control are investigated: constant switching frequency; constant turn-off current; and a combination thereof. The latter seemed to be the best. This circuit is only found suitable for loads for which the Q value is low while the temperature of the workpiece is below the Curie temperature.<>
