Full wave rectifier with RC Load

Click For Summary
SUMMARY

This discussion focuses on modeling a full wave single-phase thyristor-controlled rectifier with a parallel resistor and capacitor load. The user seeks to calculate the average output DC voltage, similar to methods used for resistive or RL loads. Key considerations include the immediate charging of the capacitor to the supply voltage upon thyristor firing and the necessity for di/dt protection for both the thyristor and the capacitor. The conversation highlights the lack of readily available resources or equations for this specific configuration.

PREREQUISITES
  • Understanding of full wave rectifiers
  • Knowledge of thyristor operation and control
  • Familiarity with capacitor charging dynamics
  • Basic principles of electrical circuit analysis
NEXT STEPS
  • Research the calculation of average output DC voltage for thyristor-controlled rectifiers

  • Study capacitor smoothing techniques in power supply design
  • Investigate modeling tools for electrical circuits, such as SPICE simulations
USEFUL FOR

Electrical engineers, power electronics specialists, and students studying circuit design and rectifier applications will benefit from this discussion.

Hi, I am trying to model a full wave single phase thyristor controlled rectifier feeding a resistor and capacitor in parallel (like a power supply I believe where the capacitor is used for smoothing?) and I would like to calculate the average output dc voltage in a similar fashion as for a resistive or RL load but I cannot seem to find a book with the equation or even the integral to be solved. Is this possible as I am struggling to find examples of it already being done?

oops i answered the wrong question deleted.

Resistor and capacitor in parallel?

Think about it ,

The capacitor will charge immediately to the supply voltage at instant thyristor fires... you'll need di/dt protect the thyristor and maybe the capacitor too..
