Phase-Locked Loop-Based Strategy for Accurate Blanking Time Allocation Around Zero-Voltage Crossings in Bridgeless PFCs
A. Pigazo, P. Lamo, F. Azcondo, C. Brañas
The totem-pole bridgeless power factor correction (PFC) is becoming a de facto standard in high-end power supply designs due to the efficiency and power density it achieves. However, bridgeless PFCs distort the line current near the grid voltage zero crossings (ZC) because of gat…
