We considered about the efficiency of the Buck+Half bridge converter. The converter provides the effective applications for a low output voltage, a high output current and a wide input voltage. Developed the Buck+Half Bridge converter ratings are of 36~72V input and 3.3V/30A output. In Half Bridge converter, the 86~96.4% of the efficiency is measured at 100kHz switching frequency with PQI core. In the case of the synchronized Buck+Half Bridge converter, the measured efficiency is higher than that of the unsynchronized coverter. In the synchronized Buck+Half Bridge, the maximum efficiency is up to 92.3% with PQI core at 100kHz, 7A output.
