Working Principle

The V375B2C100BF DC-DC converter is designed with an encased metal frame, in which there are coolers, transformers, and various electrical components, and it can convert high voltage DC to low voltage DC, which is called high-low voltage conversion. The general working principle is through signal isolation and current modulation technology. In a DC direct current, only voltage needs to be regulated to make the output stable. A feedback signal is sent to the control circuit to adjust the output current in accordance with the load.

The primary function of the DC-DC converter is to transform the DC voltage from high voltage to low voltage and ensure the stable output voltage despite changes in load capacity. The main components of the DC-DC converter include: regulating circuit, isolation transformer, DC-DC control chip, inductance, capacitance, MOS field-effect tube, energy storage capacitor, voltage-resistance attenuation circuit, circuit protection devices, etc. And the working principle is closely related to those components.

The voltage-resistance attenuation circuit works as the pre-stage circuit of the DC-DC converter. It can adjust both the input voltage and the output voltage. The input voltage and the output voltage are both adjustable, which helps to control and adjust the operation of the DC-DC converter. The DC-DC control chip is the core part of the circuit, and it controls the whole process of the signal in the circuit, and reacts to the changes of the input voltage or output current. After the signal is adjusted, the isolation transformer will play its role and transfer the signal to the downstream circuit.

The inductance and capacitance are then used to form a filter circuit that can filter out signal interference. The switches in the transformer are usually controlled by the MOS field-effect tube, and the energy storage capacitor is used to smooth the current fluctuation in the circuit. Finally, the signal is output from the voltage-resistance attenuation circuit. The protective circuit is equipped in the converter to protect it from excess current and voltage caused by the overload and over-voltage.
