Bidirectional DC to DC converter
3 year ago
DC/DC power supply
1. Working principle
Bidirectional DCDC converter is applied to new energy, which operates in cooperation with battery, battery, DC bus, motor controller and motor to realize various operation conditions of new energy, energy recovery and prolong the service life of battery.系统工
2. Function introduction
◆ Realize the two-way flow of energy, that is, it can charge from the battery side to the bus and charge the battery from the bus side
◆ It has full-automatic protection functions such as overheating, overvoltage, overload and overcurrent
◆ Original imported power devices shall be selected
◆ The main control chip adopts microchip industrial MCU and full digital circuit design
◆ All industrial chips are used, which can operate normally in cold, high temperature and humid environment.
◆ Standard RS-232 communication, RS-485, GPRS, Ethernet and other communication modes can be selected to meet the needs of different occasions to the greatest extent
