摘要
单周期控制是一种大信号、新颖的非线性PWM控制技术,其优点是能够自动消除一个周期内的稳态和瞬态误差,动态响应快,具有结构简单、控制精度高、控制性能不受电源参数变化影响。阐述了单周期控制的工作原理,并在此基础上设计了以IR1150为控制芯片的200 W功率因数校正电路。实验结果表明,该电路简单可靠,外围元件少,功率因数超过0.98,系统性能优越。
One cycle control is a large signal and new nonlinear PWM technology. This technique has the merits of eliminating error of steady and instantaneous state automatic, fast dynamic response and simple circuit structure, high control precision, control performance not affected by the variable of power parameters. This paper introduced the basic concept of one cycle control, and built a 200W circuit based on IR1150. Experiment results show that the power factor of the circuit is above 0.98, is not only simple and dependable but also less organ and high capability.
