Abstract
This article focuses on a microcontrol er to AT89S52 for controller, PWM control of the fly back pulse of the hardware switching power supply design principle and method. The system consists of the main circuit, control and drive circuits, over-current protection circuit. From the main circuit of the AC power rectifier filter circuit, DC-DC circuit and load circuit, the core of the DC-DC conversion circuits design, the circuit-circuit the use of anti-shock control to the power MOSFET to switch devices so that the load was Stable, adjustable DC.关键词
