Complex (RLC) Design Analysis Method of Zero Current Switching–Series Resonant Inverter High Voltage DC to DC Converter

Abstract

The conventional Zero Current Switching– Series Resonant (ZCS-SR) circuit has almost zero switching losses. However, it has limitations in describing precise voltage gain values at instantaneous events as the parasitic components of the circuit remain neglected. This paper presents an improved analysis design method for the LC conventional ZCS-SR inverter high voltage dc power supplies, by considering the ideal parasitic components within circuit. Furthermore, the analysis of the circuit is carried out using complex RLC design. Considering these non-idealities, we have developed a complex valued analysis design model of ZCSSR inverter high voltage dc-dc converter. This detailed model considers damping factors, parasitic losses and provides results for the entire cycle of operation. Simple analytical equations are derived, keeping the design techniques at large, to attain the essential performance parameters. This proposed analysis model has been simulated using PSPICE software. Results reveal that this analysis design model provides more than 80% efficiency.
