摘要

对于特定的感应加热应用，电路拓扑和开关策略的选择在很大程度上取决于应用的要求和加热过程中负载参数的变化。本文比较了电压馈电、全桥、串联谐振电路拓扑结构下的强制换相扫频和强制换相移控制开关策略。这是通过对恒载电流控制环的实例研究来完成的，并得到了一个解析模型的结果。在半导体额定值方面，相移控制开关策略被证明是更有效的。

Comparison of swept frequency and phase shift control for forced commutated series resonant induction heating converters

The choice of a circuit topology and switching strategy for a specific induction heating application will to a large extent depend on the requirements for the application and the variation in the parameters of the load during heating. In this paper the forced commutated swept frequency and the forced commutated phase shift control switching strategies for the voltage fed, full-bridge, series resonant circuit topology are compared. This is done by means of a case study for a constant load current control loop and the results are obtained with an analytical model. The phase shift control switching strategy proved to be more efficient regarding semiconductor ratings.
