- Abstract
- A three-phase interleaved boost converter stage of an ac-dc PFC converter that uses GaN switches is developed that utilizes a feed-forward band-stop filter control method to suppress low-frequency output voltage ripple. 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.
