The operations of power electronic converters are mainly based on the switching of power semiconductor devices. Due to this the converters introduce voltage and current harmonics into the source as well as load. These harmonics can cause problems of distortion in the output voltage and current and also electromagnetic interference with the neighboring systems. To reduce these harmonics to an acceptable level it is necessary to introduce filters on the input and output of the converter. To evaluate the performance of the converter the quality of the waveform (voltage and current) needs to be measured using factors such as total harmonic distortion (THD), harmonic factor (HF) and input power factor (IPF). The implementation of proper control algorithm in the controller, generation of harmonics and distortion in the output waveform can be reduced. The switching of the power devices in power electronic converter can cause radio frequency interference due to electromagnetic radiation as a result gating circuits may generate erroneous control signals. This interference problem can be avoided by the use of grounded shielding.

How is electronics used in thermal power plants?
Electronics are used in thermal power plants when the power from the thermal power plants are transferred to a storage source. There, electronics comes in.
What is the difference between power electronics and linear electronics?
Power electronics is study about controlling the power using electronics devices, Electronics is study about controlling the electrons flow&make amplification of electrons for required areas
What kinds of electronics use a DC power supply?
Almost all digital electronics use a AC to DC power supply. Digital electronics cannot handle AC. all electronics device having battery powered are using DC power supply http://www.wzmicro.com
What is the full form of STR in semiconductor electronics?
Power switch
What are the current trends for power electronics?
Renewable Energy and IGBT Inverters
What two voltages are present on a peripheral power connector?
What two voltages are present on a peripheral power connector?
How is electronics used in thermal power plants?

What is uninterrupted power supply?
Uninterrupted Power Supply (UPS) is a device that being used to secure the stability of power supply for the protected equipments (which are mostly IT equipments like computers and servers). If there has no UPS, sudden fluctuations of the utility power (so called raw power) will affect the business operation.

What is rated power in an electronic equipment?
it is the standard ratings of the equipments while manufacturing
What is the difference between power electronics and digital electronics?
in digital electronics, engineers use low voltages like 5 or 12 or 24 volts but when they want to transfer electrical energy in high power which means high voltage and high ampere they use power electronics . in power electronics sometimes the transistor or diode or in power electronics language IGBT and thyristor can work in 10000 volt or higher voltages
