摘要
二次型Boost变换器因其具有宽输入电压范围特性而得到广泛关注。与传统Boost变换器相比,二次型Boost变换器含有两个LC滤波器,呈现四阶动力学特性。本文提出将二次型Boost变换器输入电感电流和输出电容电压作为反馈信号的峰值电流控制策略,简化了控制环路设计。实验结果验证了峰值电流控制二次型Boost变换器具有瞬态特性好、输出电压纹波小等优点。
Wide input voltage range of quadratic Boost converter has attracted much attention recently.Compared with conventional Boost converter,quadratic Boost converter has two LC filters,thus is a four order dynamics circuit.Peak current control mode of quadratic Boost converter with input inductor current and output capacitor voltage as feedback control variable is proposed.The proposed control scheme is simple.Experimental results show that the proposed peak current control quadratic Boost converter features with fast transient response and small output voltage ripple.
