Abstract:
?Aiming at tlie application of LLCC series-jDarallel resonant circuit in high-frequency sine wave output the constant-current constant-voltage and filter characteristics of LLCC series-parallel resonant circuit were analyzed in detail. The LLCCfilter characteristics of the switching frequency of the phase- shifted full-bridge topology coinciding with the LLCCs series-parallel resonant frequency were discussed. The matliematical relationship between THD and LLCC parameters load and duty cycle were obtained. The effect of LLCC parameters on soft switching and filter characteristics was discussed in detail and the influence of parasitic parameters of transformer on LLCC circuit was discussed. The design steps of the parameters of the LLCCresonant circuit were given with THD as the index of high frequency sine wave output. The analysis was verified by the 10 kW 40 kHz sine-wave output power supply for vacuum sputtering designed according to the design guidelines, which provides effective guidance for the design of high frequency sine wave output inverter.
