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.

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
Which branch of engineering is Solar power?
electrical and electronics engineering or electronics engineering as panels are electronic material ,or may be electrical engineering which deals with power generation
What is a chopper in power electronics?
dc to dc converter
Soft switching in power electronics?
It is to open the power-switch at zero current to minimize the looses during switching.
How is electrical consumption measured for electronics?
Generally speaking, the electrical energy consumption of low-power electronics circuits is measured in watt.hours (W.h) whereas the energy consumption of household appliances and most other pieces of equipment, apparatus or machinery that take more power than items which only have low-power electronics circuits in them is measured in kilowatt.hours. (kW.h)
What does peripheral mean in electronics?

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 are the side effects of peripheral vasodilators?
Peripheral vasodilators may cause dizziness and orthostatic hypotension--a rapid lowering of blood pressure when the patient stands up in the morning.

What are the effects of electronics on your environment?
Electronics have a negative effect on the environment. This is because most of them use or are made of fossil fuels.
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
