摘要
针对传统电压单环PWM控制电路在输入电压大范围波动时存在输出电压幅值波动大、谐波分量大、动态响应较慢等缺点 ,提出了一种能够适应输入电压大范围波动的新型电压 电压PWM控制策略 ,并给出了其在Buck电路中的实际应用控制规律。仿真结果表明该新控制策略精度高 ,效果明显。
Because of the ripple of the input DC power supply in the DC/DC circuit, the output harmonic amplitude of the voltage controlled by the single voltage feedback controlled PWM converter is high, and the dynamic response is much slow. In this paper, a novel methodology to realize double voltage PWM control is presented, which is adapted to the ripple of the DC power supply system, and the control rule in Buck circuit is presented.
