This article introduces a direct mapped method (DMM) for real-time simulation of high switching frequency resonant converters, which 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 up to 500 kHz, achieving a 25-ns simulation time-step for a wide range of clock frequencies, ranging from 40 to 320 MHz.
This article 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 field programmable gate array (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 to 320 MHz.
