摘要：
In this paper, a new light-emitting diode (LED) driver based on full-bridge series resonant converter (SRC) is presented. In the proposed converter LED, load is placed in between DC source and the input side of the full-bridge inverter which reduces the rectifier components of the SRC. The proposed converter reduces the number of diodes used for rectification and ensures zero voltage switching of the power switches which improves the efficiency of the converter. LED lamp current is regulated with phase-shift pulse width modulation (PWM) of full-bridge. Lamp illumination is controlled with PWM dimming. The operation and mathematical analysis of LED driver is presented. To validate the proposed concept, a 40-W laboratory prototype is developed. Experimental results are presented. Peak efficiency of 93% is obtained.
