Product Description

 

Product Description:

 

Programmable bidirectional DCDC converter is a device to realize the bidirectional flow of DC energy, which is mainly used in hybrid electric vehicles, DC uninterrupted power supply system, new energy, automotive motors, electronic control testing, power battery pack charging and discharging testing, power electronics testing and other fields.

The bidirectional DCDC converter adopts the classic BUCK/BOOST circuit topology and has the function of bidirectional switching of up and down voltage, namely the up and down chopper circuit. When the energy flows from C1 to C2, the DC converter works in BOOST mode to realize the boost function. When the energy flows from C2 to C1, the DC converter works in BUCK mode to realize the buck function.



Bidirectional DCDC converter is the dual quadrant operation of DC-DC converter, its input and output voltage polarity is unchanged, but the direction of the input and output current can be changed. The output state of the converter can be changed in the first and second quadrants of the Vo-lo plane. The converter input and output port exchange can still complete the voltage conversion function, power can flow from the input end to the output end, and can also flow from the output end to the input end. According to various basic converter topologies, bidirectional energy flow can be realized by replacing unidirectional switch with bidirectional switch.
