摘要
提出了在串联谐振逆变器中谐振极的一种设计方法及其实验结果。谐振极电容对串联谐振感应加热电源的影响可用一个实际电流源的方程式表示。利用该方程式及其改进形式,可以很容易地选择合适容量的电容器,并决定相应的最小触发角。实验结果表明,一个合适的谐振极电容,可以减小开关损耗,该设计方法适合于为串联谐振逆变器设计谐振极电容。
In this paper, a design method and its experimental results of the resonant pole in the series resonant inverter are presented. The influence of the resonant pole capacitor on the power supply for series resonant inductive heating isexpressed in form of the equation of a practical current source. Using this equation and its reformed expression, the reasonable value of the capacitor can be easily selected and corresponding minimum trigger angle can be determined. The experimentalresults show that the switching losses may be decreased with a suitable resonant poe capacitor, and this method issuited to design the resonant poe capacitor for series resonant inverter.
