title = "THD Analysis and Switching Frequency Optimization for A Novel ACRP based High-Precision DC-AC Converter",
abstract = "Total Harmonic Distortion (THD) is an important parameter for measuring the performance of high-precision power amplifiers. Both switching frequency and dead-time affect the magnitude of THD. This paper focuses on the traditional half-bridge and Auxiliary Commutation Resonant Pole (ACRP) parallel half-bridge circuits. First, the harmonic components caused by SPWM modulation are analyzed considering the filter. Then, the low-order harmonics introduced by the dead-time are calculated. Based on these harmonic components, the THD is computed. The analysis shows that the ACRP parallel half-bridge scheme can reduce THD by increasing the switching frequency and eliminating the dead-time. The relationship curve between THD and switching frequency is plotted, and the theoretically optimal switching frequency range for minimum THD is obtained. Finally, a simulation circuit is built to validate the correctness of the mathematical model.",
