If the diodes in a rectifier circuit are replaced by SCRs, you have the makings of a controlled rectifier circuit, whereby DC power to a load may be time proportioned by triggering the SCRs at different points along the AC power waveform. The TRIAC Phase Controlled Rectifier Circuit Operation and Its ... The term PCR or Phase controlled rectifier is a one type of rectifier circuit in which the diodes are switched by Thyristors or SCRs (Silicon Controlled Rectifiers). Whereas the diodes offer no control over the o p voltage, the Thyristors can be used to differ the output voltage by adjusting the firing angle or delay.

Rectifier Circuits IIT Bombay Rectifier Circuits Introduction We have studied the operation and I V characteristics of a PN junction diode in the previous experiment. We have seen that the diode can conduct only when it is forward biased and blocks when it is reversed biased. This property of diode makes it an essential component of Power Management, Chapter 7: Voltage Regulator ICs In Fig. 7 13, the PWM control turns the MOSFET on and off. Without feedback, the PWM duty cycle determines the output voltage, which is twice the input for a 50% duty cycle. Stepping up the voltage by a factor of two causes the input current to be twice the output current. In a real circuit with losses, the input current is slightly higher. 7 13.
