Answer:
To rectify in buildings for high power circuits we use Thyristor controlled Rectifier which is major part of Power Electronics. This type of resistors are used for controlling operations and gating methods are used for this purpose the main reason for using these type of rectifier is because diodes have low range of voltage and current but thyristors have higher range of working and these rectifier can be controlled.
A thyristor is a semiconductor device which can be used to switch current on and off. When used in rectifier circuits, thyristors allow current to be controlled more accurately than diodes, which can only be ON or OFF. A thyristor can be triggered to allow current to pass in a graduated manner, by firing (switching on the thyristor) at a precise time, therefore controlling the conduction angle. The level of control required for a given application will determine how thyristors are used in the circuit. Half-controlled rectifiers use thyristors in place of diodes on either the positive or negative side of the circuit, whereas a fully controlled rectifier uses thyristors entirely
