Switching three-level DC converter circuit

DC converters are divided into two types: parallel DC converters and non-parallel DC converters. The parallel DC converter adopts advanced high-frequency pulse width modulation edge resonance technology, which greatly improves the efficiency. The whole machine has the characteristics of high voltage stabilization accuracy, fast dynamic response, low output noise, strong anti-interference ability, and wide operating temperature range. The Chinese LCD on the panel can display the working status of the power module, and can also visually display data such as voltage and current; the module has various protection functions; the module has built-in equalizing charging and floating charging switching circuits, and can choose manual or automatic control. The monitoring interface can monitor the working status of the module, perform on/off control, and equalize and float charge control. It is also equipped with an automatic current sharing bus interface and an equalizing charge bus interface. The smart model is equipped with an RS485 interface, which can be connected with supporting monitoring modules, PCs, PLDs and other smart devices to complete remote monitoring and realize four remote functions of the power system. The non-parallel DC converter is composed of imported DC-DC modules, which has the advantages of high voltage stabilization accuracy, low output noise, strong anti-interference ability, etc., and is small in size and light in weight.
