面向负载点变换器的参数不敏感混合信号滞环带电流控制

The inductor current ripple under hysteresis current control is sensitive to system as well as controller parameters, which often deviates from the desired band. Thus, a phase-locked-loop (PLL) is employed to regulate the switching frequency over the operating range. Digital platform drastically simplifies this using an all-digital PLL (ADPLL) and offers the controller-tuning flexibility for impro...
