Computation of Losses in the Passive Components in Zero Current Switch (ZCS) and Zero Voltage Switch (ZVS) Topologies of Resonant Converters

摘要

The paper presents a mathematical model to compute the losses in the passive components in ZCSrnand ZVS Resonant Converters by expressing the values of all passive components, the conversionrnfrequency, the flux densities in the inductor cores, the currents in windings and capacitors in terms ofrnthe input and output voltages, the output current and ripple factor, the resonant frequency and the ratiornof peak switch current to output current for ZCS or that of peak switch voltage to input voltage for ZVS.
