A Direct Mapped Method for Accurate Modeling and Real-Time Simulation of High Switching Frequency Resonant Converters

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 noniterative solution network equations. proposed method is implemented on FPGA simulate LLC converter with frequencies ranging up 500 kHz. best reported implementations achieve 25 ns time-step wide range clock frequencies, from 40 MHz 320 MHz.
