Nowadays, with the rapid development of the consumer electronics, the power density of the power supply adapter is going to be much higher. To reduce the voltage stress on secondary-side rectifiers and the secondary-side conduction loss, the capacitive output filter is widely used, in the half-bridge LLC resonant converter and in the soft-switched phase-shift full-bridge converter with primary-side energy storage inductor for instance. However, compared with the inductance output filter, the capacitive output filter usually leads to relative large output current ripple, which makes the secondary-side leakage inductance of transformer suffer from the considerable volt-second balance. Thus, the practical voltage stress on the secondary-side rectifier should be considered more carefully. This paper shows the detailed analysis and evaluation for the leakage inductance effects of two front-end Dc/Dc converters with capacitive output filters. Some design considerations are also given for the engineers.
