Abstract:In this letter, a new zero-current-switching (ZCS) dual-channel push-pull isolated resonant gate driver (DPIRGD) is proposed to drive a pair of power mosfet in one bridge leg operating at high-switching frequency. The characteristics of the proposed DPIRGD include capability to provide two isolated complementary drive signals, low-gate drive loss, and high reliability of the turn-off status. Compared to the previous gate driver suitable for the zero-voltage-switching full-bridge converters, the proposed DPIRGD achieves similar gate drive loss but implements low components enabling to reduce the drive cost and increase the reliability. The operation principle, loss analysis, optimum design, and comparison study of the DPIRGD are presented in detail. The experimental results are shown to verify the effectiveness of the proposed concept. This solution has achieved nearly 70.7% reduction in gate drive power loss compared to the conventional voltage-source drive circuit. © 1986-2012 IEEE.
