Analysis of a hybrid series parallel resonant bridge converter

摘要

The steady-state operation of a hybrid series parallel resonant bridge is analyzed. Two expressions are derived for the power output as a function of capacitor ratio, switching frequency, and conversion ratio. One power output expression is for conversion ratios less than or equal to one, and the other expression is for conversion ratios greater or equal to one and less than or equal to two. The optimum conversion ratio for maximum power transfer is also derived.
