VOLTAGE REGULATION MODULE, CHARGING MODULE, AND CHARGING PILE

This application discloses a voltage regulation module, a charging module, and a charging pile that may be used to charge an electric vehicle, to regulate an output voltage in a wide range, and implement seamless switching without power-off in a process of switching from a low-voltage output state to a high-voltage output state. The voltage regulation module includes a first DC/DC converter group and a second DC/DC converter group. Both a parallel circuit and a series circuit exist between the first DC/DC converter group and the second DC/DC converter group. In addition, a controllable switch group is disposed in each of the series circuit and the parallel circuit, and a semiconductor power transistor group is connected in parallel with two terminals of each controllable switch group.
