Peak inverse voltage in AC to DC converter system

The peak inverse voltage (PIV) is the maximum voltage that appears across a diode or a switching device when it is reverse biased. In an AC to DC converter system, the PIV is an important parameter to consider as it affects the selection and rating of the components used in the circuit.


Different types of AC to DC converter systems

There are various types of AC to DC converter systems available, such as:



  • 3-phase bridge converter

  • 3-phase half-wave converter

  • Single-phase full wave mid-point converter

  • Single-phase full-converter



Comparison of PIV in different converter systems

Among the given options, the single-phase full wave mid-point converter has the highest PIV. This can be understood by analyzing the operation of each converter system.



  • 3-phase bridge converter: This converter system uses a bridge configuration of diodes to convert AC to DC. The PIV across each diode is equal to the peak line-to-line voltage of the AC input.

  • 3-phase half-wave converter: In this converter system, only half of the AC input waveform is converted to DC. The PIV across each diode is equal to the peak line-to-neutral voltage of the AC input.

  • Single-phase full wave mid-point converter: This converter system uses a center-tapped transformer and two diodes to convert AC to DC. The PIV across each diode is equal to the peak line-to-neutral voltage of the AC input, which is higher than the peak line-to-line voltage in the bridge converter.

  • Single-phase full-converter: This converter system uses four diodes to convert AC to DC. The PIV across each diode is equal to the peak line-to-line voltage of the AC input.



Conclusion

Based on the analysis, it can be concluded that the single-phase full wave mid-point converter has the highest PIV among the given options. Therefore, option 'C' is the correct answer.
