基于FPGA的均匀PDM感应加热电源的研究

Research on Symmetrical PDM Heating Power Supply Based on FPGA

针对传统脉冲密度调制(PDM)调功方式的不足,提出了一种均匀脉冲分配方法,使得控制脉冲在一个工作周期内分布更加均匀,并在现场可编程门阵列(FPGA)内采用状态机的方法产生了此均匀控制脉冲。最后通过感应加热电源实验样机对结果进行了验证。

This paper proposes a symmetrical pulse distribution method for the shortage of traditional pulse density modulation（PDM） ,which makes the control pulses more symmetrical distribution.The control pulses are generated by using the state machine approach in field programmable gate array （FPGA） and the results are verified by induction heating power experimental prototype.
