Abstract
This paper presents zero current switching (ZCS) - series resonant (SR) inverter fed, high voltage DC-DC converter with theoretical and practical analysis. The ZCS condition for switching attains almost zero switching losses. Moreover, parasitic oscillations are reduced within the circuit by the resonant tank. Capacitive output filter provides advantages to the circuit, as it is preferred with higher voltage applications.However, at first the peak currents and voltages are a bit problematic, as slight variations in the output voltage and operation at light loads provide limitations to the converter, second the parasitic components within the tank, as the parasitic capacitance and inductance, result into parasitic losses. The system has been analyzed using PSPICE software simulations with practical presentation and implementation of the design. The obtained results show that the system has several advantages such as wide range of output voltage control, low output voltage ripple over the entire range and low current stress at light loads; on the contrary the design confronts limitations at peak instants and small loads
