Abstract
A module of suppressing inrush current, a method of controlling the module of suppressing inrush current and an on-board bidirectional charger using the same are provided. The on-board bidirectional charger includes a PFC-inverter module and the module of suppressing inrush current, and the module of suppressing inrush current includes a controlled switch and a suppressor of suppressing inrush current connected in parallel with the controlled switch. The charging and inverting circuits are fully multiplexed, which solves the problem that a high-power on-board charger under harsh AC power supply environment in bidirectional charging cannot provide special protection against inrush current, and can improve power density and circuit efficiency of charging and inversion, realize isolation function including reducing EMI electromagnetic interference and reducing switching interference signals, realize more convenient buck/boost functions, improve using life and performance of devices, reduce cost, and reduce the size of equipment.
