摘要: A field-programmable gate array (FPGA)-based digital control boost power factor correction (PFC) AC-DC converter with average current-mode (ACC) and load-current-injection is proposed to achieve high improve dynamic performance. The ACC-controlled includes a fast inner current loop slow outer voltage loop. regulates the input such that follows comply standards on distortion of supplies. maintains output at reference level against load variation line fluctuation. main limitation PFC rectifiers bandwidth only about 10–20 Hz. technique applied speed up response variation. 350 W prototype built validate experimental results are provided verify complying IEC 61000-3-2 Class D regulation
