Switching three-level DC converter circuit

The DC converter is divided into two types: a parallel DC converter and a non-parallel DC converter. The parallel DC converter uses advanced high-frequency pulse width modulation edge resonance technology to greatly improve efficiency. The whole machine has the characteristics of high voltage regulation precision, fast dynamic response, low output noise, strong anti-interference ability and wide operating temperature range. The Chinese liquid crystal on the panel can display the working status of the power module, and can also display the voltage and current data visually; the various protection functions of the module are complete; the module has built-in equalization, floating charge switching circuit, and can choose manual or automatic control. The monitoring interface can monitor the working state of the module, can be controlled by the switch machine, all float control, and is equipped with an automatic current sharing bus interface and a charging bus interface. The intelligent model is equipped with RS485 interface, which can be connected with other intelligent devices such as supporting monitoring module, PC, PLD, etc. to complete remote monitoring and realize the four remote functions of the power system. The non-parallel DC converter is composed of imported DC-DC module, which has the advantages of high voltage regulation precision, low output noise and strong anti-interference ability, and is small in size and light in weight.
