This paper presents a general pulse generator application specific integrated circuit (ASIC) for power electronics devices designed with the large-scale programmable logic devices. Based on the phase sealer with the step of 0. 1 degree, the ASIC can generate the single-trigger pulse signals with the adjustable starting phase and pulse width and also has output of the pulse-width modulation (PWM) pulse sequences according to the pulse data. With a PWM pulse data computation module, its pulse signal outputs can be controlled by itself rather than by the external pulse data input. It is easy to realize synchronization with the aid of an all-digital phase-locked loop in the ASIC. Besides, this ASIC has the characteristics of flexible pulse conditioning, manifold operation modes, visualized monitoring, effective data access management. A general pulse generator circuit board is developed on the basis of the ASIC. The board and the ASIC can be used in many power electronics applications and can improve the digital and integrated level of the controllers for these applications.
