摘要:

提出了一种用于高开关频率谐振变换器实时仿真的直接映射法。DMM将状态变量与二极管状态联系起来,并为网络方程提供精确的非迭代解。该方法在FPGA上实现,以模拟开关频率范围高达500 kHz的LLC变换器。最好的DMM实现报告实现了25 ns的仿真时间步长的时钟频率范围很宽,从40 MHz到320 MHz。

英文摘要:

This paper presents a Direct Mapped Method (DMM) for real-time simulation of high switching frequency resonant converters. The DMM links state variables to diode statuses and provides an exact and noniterative solution to network equations. The proposed method is implemented on FPGA to simulate an LLC converter with switching frequencies ranging up to 500 kHz. The best reported implementations of DMM achieve a 25 ns simulation time-step for a wide range of clock frequencies, ranging from 40 MHz to 320 MHz.
