What is a three-phase full wave controlled rectifier?

What is a three-phase full wave controlled rectifier?

three phase full converter is a fully controlled bridge controlled rectifier using six thyristors connected in the form of a full wave bridge configuration. All the six thyristors are controlled switches which are turned on at a appropriate times by applying suitable gate trigger signals.

What is the efficiency of 3-phase full wave rectifier?

The advantage of 3 phase full wave rectifiers is that the output voltage is regulated and do not falls to zero. The output voltage is maintained between 86.6% of the maximum voltage and the peak value of the voltage.

What are the applications of controlled rectifier?

SCRs are mainly used in devices where the control of high power, possibly coupled with high voltage, is demanded. Their operation makes them suitable for use in medium- to high-voltage AC power control applications, such as lamp dimming, power regulators and motor control.

What is the advantage of three-phase rectifier?

Advantages of three-phase rectifier over a single-phase rectifier: The transformer utilization factor is high. More efficient than a single-phase system. The power output and therefore rectification efficiency are quite high.

What is full wave controlled rectifier?

The full-wave rectifier is more efficient than the half-wave rectifier as it uses both half-cycles of the input sine wave producing a higher average or equivalent DC output voltage. A disadvantage of the full-wave bridge circuit is that is that it requires four diodes.

What is a full controlled rectifier?

• The single phase fully controlled rectifier allows conversion of single phase AC into DC. Normally this is used in various applications such as battery charging, speed control of DC motors and front end of UPS (Uninterruptible Power Supply) and SMPS (Switched Mode Power Supply).

What is phase controlled rectifier circuit?

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.

What are the advantages of full wave controlled rectifier?

Advantages of full-wave rectifier: Efficiency is higher. The large DC power output. Ripple factor is less. The ripple voltage is low and the higher frequency in case full-wave rectifier so simple filtering circuit is required.
