Product overview:

BD series high-precision bi-directional DC power supply is a bi-directional charging and discharging 

device. It adopts two-stage conversion structure IGBT type high-precision, highly reliable, programmable 

and automatic DC power supply. Its DC output features high-precision and high dynamic response, and 

has automatic bi-directional operation function. It adopts full digital control, with high control accuracy, 

fast response speed, wide output adjustment range, and programmable output, It can be applied to many 

occasions through different controls.

Product features：

(1) Built in AC isolation transformer+LC AC/DC filter, input and output are electrically isolated.

(2) Infineon high-voltage IGBT module is used for two-stage conversion and pure digital power frequency 

isolation power supply.

(3) Energy can be fed back to the power grid: it has both power and load characteristics.

(4) DCDC side adopts carrier phase-shifting circuit, so that the DC output side has higher precision and 

smaller ripple.

(5) It can realize the characteristics of wide output voltage range, high precision and fast dynamic response.

(6) The output has constant voltage, constant voltage current limiting, constant current, constant power and

constant resistance modes.

(7) High voltage film capacitor is selected as DC support capacitor, with reliable performance and long service life.

(8) DC output side adopts high-voltage DC fuse for effective short-circuit protection.

(9) The main control part of the power supply adopts a full digital control circuit, and the main control chip is a

TI DSP chip.
