摘要

本文提出了在微电网(MG)应用的单电感双输出(SIDO)背景下使用线性辅助开关电源变换器。通过将DC/DC纹波控制开关电源变换器与每个输出端的电压线性稳压器相结合,可以提高负载和线路调节的性能。为了实现这一目标,提出了一种电流转向开关策略,以及一种资源感知电路的实现。基于纹波的迟滞控制使开关频率可变,从而保证临界导通模式(CCM和DCM的边界)。

On Single-Input Dual-Output (SIDO) DC/DC Multi-Port Converters for DC Microgrid Applications
This paper proposes the use of linear-assisted switching power converters in the context of single-inductor dual-output (SIDO) for microgrids (MG) applications. By combining a DC/DC ripple-controlled switching power converter with the respective voltage linear regulators at each output, improved performance in terms of load and line regulations is obtained. To achieve that aim, a current-steering switching policy is proposed, together with a resource-aware circuit implementation. The ripple-based hysteretic control results in variable switching frequency to guarantee critical conduction mode (boundary of CCM and DCM).
