There are several low power devices belong to Thyristor family that are mainly used in trigger circuits to turn the thyristor ON.
Controlled rectifiers, or converters, as they are generally called, are broadly classified into full-controlled and half-controlled types.
The ratings of a semiconductor device give the values for the various conditions that a manufacturer recommends for reliable operation of the device.
The maximum power that can be controlled by a single SCR is determined by its rated forward current and rated forward blocking voltage.
The maximum power that can be controlled by a single SCR is determined by its rated forward current and rated forward blocking voltage.
Rectification is the process of converting alternating current or voltage into direct current or voltage. An uncontrolled rectifier uses only diodes as the rectifying elements.
A single-phase, half-wave rectifier is not very practical due to its low average output voltage, poor efficiency, and high ripple factor.

This is the circuit diagram of a simple UPS that can deliver 12V unregulated and 5V regulated DC. The transformer T1 steps down the mains voltage to 12V AC and then the bridge B1 rectifies it.
Some time disturbance of power supply creates a number of problems. Especially in sensitive departments such as Radar System, Hospitals, Telephone exchanges and industries etc.
An Inverter is a device that converts 12 volts dc to 120 volts ac, which is what we use in our homes. This project will handle about 300 watts, which is perfect for lights, small T.V.'s and radio
Transformer is a magnetic circuit whose name is derived from its ability to transform (i.e. change) the magnitude of an AC voltage applied to it
