Application Field of V72B3V3H100B

V72B3V3H100B is a wide-input, high-efficiency, ultra-high-voltage, high-power DC-DC converter, suitable for DC field power supply systems, such as telecommunications infrastructure, industrial automation, security and military systems, and ships and electricity. Industry.

V72B3V3H100B has the characteristics of large dynamic range of wide input voltage range, high efficiency, or high efficiency, strong anti-interference ability, high accuracy of voltage, fast response speed, flexible combination and diversified protection functions. Especially suitable for high power DC field power supply of high precision control, relatively harsh working environment and specified special requirements.

Working Principle of V72B3V3H100B

The general working principle of V72B3V3H100B is the principle of buck converter, that is, the switch is placed between the input and output. When the switch is closed, the input current passes through the switch, and the output current is zero. When the switch is opened, the input current is cut off, the output current will flow, and the inductor will store energy.

The control loop of the converter usually consists of a controller, a driver and a main switch. The controller transmits the corresponding PWM signal to the drive, and the drive controls the main switch through the PWM signal. Each time the main switch is switched, the energy stored in the inductor is converted to the output.

The voltage and current of the input and output can be adjusted by adjusting the duty cycle, frequency and current limit of the switch. In general, the duty cycle of the switch, the output voltage should be equal to Input voltage multiplied by the duty cycle proportion.

Conclusion

V72B3V3H100B is a novel DC-DC converter with wide input voltage range, high efficiency, strong anti-interference capability and high accuracy of voltage. Its application fields are mainly in DC field power supply systems. Its working principle is the principle of buck converter, that is, the switch is placed between the input and output, and the duty cycle, frequency and current limit of the switch can adjust the voltage and current of the input or output.
