To increase power density, the converter switches at 500 kHz, operates in triangular current mode (TCM) to achieve zero voltage switching (ZVS), and uses GaN switching devices. A 1-kW laboratory prototype was designed and tested to verify feasibility. With the proposed controller, output ripple was reduced by 70%. Overall efficiency is greater than 96.5% and power density is 65.028 W/in3. © 2017 IEEE. |
