Bidirectional DC power supply

2024-09-26
Bidirectional DC power supply has the functions of programmable DC power supply and energy feedback DC electronic load. It can be used as a programmable DC power supply to provide precise and stable voltage and current for electronic devices, helping researchers better simulate various practical working conditions and improve product stability and reliability. At the same time, bidirectional DC power supply can also be used as an energy feedback DC electronic load, with energy feedback function. It can also feedback the excess energy generated to the power grid, reducing energy waste and lowering laboratory operating costs.
Our bidirectional DC power supply has two working states: source and load. When used as a DC power supply, the equipment provides energy to the outside in the source state. When used as a load, the device absorbs external energy and is in a loaded state. The transition between source and load states is determined by the output voltage of the device and the external voltage. When the output voltage is higher than the external voltage, the device is in the source state. When the output voltage is lower than the external voltage, the device is in a loaded state
The device can achieve three working modes: CV (constant voltage), CC (constant current), and CP (constant power) in both source and load states.
When in CV (constant voltage mode), the main interface status bar displays "CV", and the DC port voltage of the device is adjusted according to the set value. When the output or input current of the DC port exceeds the set current values of the source and load, the device will enter CC (constant current mode) and the status bar will display "CC". The output and input currents can be changed by setting the current values of the source and load respectively, and the device port voltage is determined by the external source and load; When the external power exceeds the set power values of the device source and load, it will enter the CP (constant power mode) status bar and display "CP". The power can be changed by adjusting the device source and load to set the power value.
