摘要：
A hybrid DC/DC converter is studied for direct current microgrid applications to have benefits of low switching losses with wide range of operation load, less winding turns of transformer secondary side, low ripple current on output side and high circuit efficiency. The studied converter includes a phase-shift pulse-width modulation full-bridge circuit and a half-bridge circuit to reduce the switching losses at lagging-leg switches. In the secondary side of the studied converter, two inductors, four diodes and two transformers are adopted to perform partial ripple current reduction and minimise the winding turns. The studied converters are verified with a 1200 W prototype by the experimental results.
