A hybrid compensation scheme based on variable output capacitance is proposed to improve the start-up speed and anti-load impact capability of a non-ideal peak current mode (PCM) Buck converter, under which the loop stability and dynamic response performance are ensured while realizing the synchronous switching of output capacitance and loop compensation parameters. A complete small-signal model of the non-ideal PCM Buck converter is established, the open-loop transfer function of the system is analyzed to obtain the influence of different output capacitance parameters on the compensation network, and the design of reasonable loop compensation is carried out. Simulation results show that the compensated system can maintain the crossing frequency around 10 kHz (1/20 fsw) and the phase margin around 70° under a variety of conditions. Moreover, a synchronous switching circuit of output capacitance and compensation parameters is designed. Finally, a 15 W experimental prototype was built, and experimental results further verified the feasibility of the proposed scheme.

为提高峰值电流模式PCM(peak current mode)控制非理想Buck变换器输出端的启动速度和抗负载冲击能力,提出1种基于可变输出电容的混合补偿方案。该方案在保证环路稳定性和动态响应性能的同时实现了输出电容和环路补偿参数可同步切换。建立PCM控制非理想Buck变换器的完整小信号模型,分析系统的开环传递函数受到不同输出电容参数对补偿网络的影响,并进行合理的环路补偿设计。仿真结果表明,补偿后的系统在不同条件变化下,穿越频率和相位裕度都能保持在10 kHz(1/20 fsw)和70°左右。设计输出电容参数和补偿参数同步切换电路,搭建15 W实验样机,实验结果进一步验证了所提方案的可行性。

为提高峰值电流模式PCM(peak current mode)控制非理想Buck变换器输出端的启动速度和抗负载冲击能力,提出1种基于可变输出电容的混合补偿方案。该方案在保证环路稳定性和动态响应性能的同时实现了输出电容和环路补偿参数可同步切换。建立PCM控制非理想Buck变换器的完整小信号模型,分析系统的开环传递函数受到不同输出电容参数对补偿网络的影响,并进行合理的环路补偿设计。仿真结果表明,补偿后的系统在不同条件变化下,穿越频率和相位裕度都能保持在10 kHz(1/20 fsw)和70°左右。设计输出电容参数和补偿参数同步切换电路,搭建15 W实验样机,实验结果进一步验证了所提方案的可行性。

峰值电流模式控制  /  Buck变换器  /  环路补偿  /  稳定性

A hybrid compensation scheme based on variable output capacitance is proposed to improve the start-up speed and anti-load impact capability of a non-ideal peak current mode (PCM) Buck converter, under which the loop stability and dynamic response performance are ensured while realizing the synchronous switching of output capacitance and loop compensation parameters. A complete small-signal model of the non-ideal PCM Buck converter is established, the open-loop transfer function of the system is analyzed to obtain the influence of different output capacitance parameters on the compensation network, and the design of reasonable loop compensation is carried out. Simulation results show that the compensated system can maintain the crossing frequency around 10 kHz (1/20 fsw) and the phase margin around 70° under a variety of conditions. Moreover, a synchronous switching circuit of output capacitance and compensation parameters is designed. Finally, a 15 W experimental prototype was built, and experimental results further verified the feasibility of the proposed scheme.
