pulse width modu uninterruptible power supply system
Abstract
Uninterruptible Power Supply (UPS) is a continuous uninterrupted power supply equipment. UPS is the high-performance line of anti-jamming capabilities, dynamic response to quick recovery, small harmonic voltage levels, Output voltage and frequency stability and easy to operate. It is widely used to supply power to high quality requirements to ensure that the operational performance and safety, reliable various occasions. Such as : for PC-based controller to the various industrial automatic control system, the intelligent high precision equipment such.
This paper describes a cycle without compensation deadbeat control uninterruptible power system, it has high reliability and less wear and tear, high efficiency, simple structure of the main circuit, the output filter size and light weight, a series of computer monitoring features. Periodic compensation control and no deadbeat control algorithm, 2 respectively by 8098 as a non-deadbeat PWM controller and the controller parameters detection. In addition, the paper also includes a laboratory simulation and the experimental results.
Keywords : ups、 PWM、 the cycle of compensation、 no deadbeat
