This study proposes a fast voltage-dip detection method with a single-phase phase-locked loop (PLL), which is always included in the control circuit of a bidirectional battery charger for electric vehicles with a power quality compensator. The basic principle of the proposed fast voltage-dip detection method using single-phase PLLs is discussed in detail. The detection time is theoretically derived and compared using two types of single-phase PLLs. A digital computer simulation was implemented to confirm the validity and practicability of the proposed fast voltage-dip detection method with the PSIM software considering IEC61000-4-11. A prototype experimental setup was constructed and tested, where IEC61000-4-11 was considered. The simulation and experimental results demonstrate that the proposed detection method detects the voltage dip rapidly and correctly. The simulation and experimental results also demonstrate that the detection times in the simulation and experimental results agree well with the theoretical values.
