PFC应用中的超快速动态响应与电流谐波抑制

This article introduces a digital zero crossing voltage control (ZCVC) strategy designed for general power factor correction (PFC) applications. The ZCVC approach performs voltage control calculations and updates the current reference precisely at input voltage zero-crossings. This timing ensures that the control output remains constant for each half-grid cycle, resulting in a pure sinusoidal ac c...
