| 摘 要： | 开关电源和线性电源相结合的混合电源可以提高动态响应速度，但是传统的控制方式不能有效抑制输入电压扰动的影响．为了改善混合电源对输入电压干扰的抑制能力，提高控制精度，提出了一种单周控制的混合电源，该控制方式采用单周控制对混合电源中的开关电源进行控制．理论分析结果表明，采用单周控制的混合电源能有效抵制输入电源扰动对输出电压的影响，提高混合电源的控制精度，简化电路的复杂性．仿真结果证明了这种基于单周控制的线性开关混合电源理论的正确性和有效性．

| Abstract: | A hybrid power supply is composed by both a linear and a switching source connected in parallel and it can improve the dynamic response. But the hybrid power supply cant not effectively reject the perturbations in the power supply. A hybrid power supply based on one cycle control theory is proposed in order to improve the capability and the control precision. A switching source based on one cycle control is adopted in the hybrid power supply. The analysis results indicate that the hybrid power supply can effectively reject the perturbations in the power supply. And the analysis results also show that not only the control precision is improved, but also the control circuit is simple. The simulation resuits given verify the correctness and effectiveness of the proposed method. |
