Power Electronics Laboratory
Power electronics deals with the application of solid-state power semiconductor devices for the control and conversion of electric power. Conversion techniques require the switching on and off of power semiconductor devices. Power electronics have already found an important place in modern technology and are now used in great variety of applications with power levels ranging from watts to mega-watt. Such applications include, heat controls, light controls, motor control, power supplies, vehicle propulsion systems and high voltage direct current (HVDC) systems.
Modern power electronics started with the invention of the Silicon Controlled Rectifier (SCR) commonly known as thyristor in 1956. The SCR is a four layer PNPN device with three terminals: Anode, Cathode and Gate. It is operated as a bistable switch operating from non-conducting (OFF) state to conducting (ON) state or vice versa. It is driven to conducting state by applying a gating signal to the gate when the anode is positive with respect to the cathode. Once a thyristor is in a conduction state, the gate has no control and it continues to conduct. It is turned off by reducing the anode current to zero.
At present, a number of power switching semiconductor devices are available; these devices include Power Bipolar Junction Transistor (BJT), Power MOSFET, Insulated Gate Bipolar Transistor (IGBT), Gate turn off thyristor (GTO) etc. All these devices are turned ON or OFF through the control terminal, either base or gate as the case may be. This makes the power control circuitry simpler, since these devices do not require electronics in last two decades, have greatly simplified the necessary control circuitry for power electronics equipment. The developments in the areas of power semiconductor devices, micro electronics and control techniques, in the recent past have made the power electronic equipments more reliable and acceptable for a variety of applications.
For the control of electronic power or power conditioning, the conversion of electric power from one form to another is necessary and the switching characteristics of the power devices permit these conversion. The static power converters perform these functions of power conversion.
The power electronics circuits may be classified into the following types:
- Diode Rectifiers
- AC-DC Converters (Controlled Rectifiers)
- AC-AC Converters (AC Voltage Regulators)
- DC-DC Converters (DC –DC Choppers or Switched Mode Power Supplies)
- DC-AC Converters (Inverters)
- Static Switches
