Problems solved by technology

[0002] At present, with the country's strong support for the development of the new energy industry, new energy vehicles have achieved sustained development in the country, but with the increasing travel needs of new energy car owners, the frequency of new energy vehicles used in people's daily life has increased. The safety of electricity consumption has become a concern of new energy car owners. Therefore, higher requirements are put forward for the power supply of the charging device. A stable switching power supply is required. Especially in the case of short circuit, it may burn important parts of the car and cause huge damage. Economic losses may cause casualties in severe cases, so the voltage regulation control of the power supply voltage is an urgent problem to be solved
