Controlled Rectifiers
These are the notes on most important section from power electronics that is controlled rectifiers. Controlled rectifiers are rectifiers designed using power electronics switches. Power electronics possess a weightage of 9-10 marks for GATE examination.
3 phase controlled rectifiers
The 3-phase half wave converter combines three single phase half wave controlled rectifiers in one
Turn on and off methods
The voltage reverses every half cycle in an ac circuit, so that an SCR in the line would be reverse biased every negative cycle and would turn off. This is called phase commutation or ac line commutation. To create a reverse biased voltage across the SCR, which is in the line of a dc circuit, capacitors can be used.
Power electronics notes
Power electronics is the application of solid-state electronics to the control and conversion of electric power. The first high power electronic devices were mercury-arc valves
