Working Principle

The working principle of the VB30M120CHM3/I is simple. It is a three-phase diode rectifier. The diode rectifier utilizes a series of N–Channel MOSFETs, one for each input lead, which is set to 0V during the ON-state. The MOSFETs are designed to protect the circuit from voltage transients on the input power and hence it provides surge current capability. When the circuit is in OFF-state, the MOSFETs are set to the respective supply voltages and thus no current can pass through the device.

In the ON-state, the MOSFETs switch on and the current flows through the rectifier diode. As it progresses through the diode, the current is diverted away from the load. Thus, the output current is limited and the circuit is protected from potential overload and/or over current conditions.

The rectifier diode also provides insulation between input and output lines. This separation of voltage helps to ensure that the output voltage is not affected by the voltage of the input signal. The superior surge current capability also ensures that the output voltage remains within acceptable tolerances even under extreme operating conditions.

Conclusion

The VB30M120CHM3/I is an excellent solution for high or medium power DC-DC converter, AC-DC adaptor, SMPS and resonant applications. With its excellent surge current capability, the device is able to provide reliable and efficient power conversion even under the most demanding operating conditions. As a result, the device is well suited for a wide variety of applications.
