Advantage and Disadvantage of Power Electronics

Advantage of Power electronics

Power electronics is used in space shuttle power supplies
Since there is very low loss in power electronic devices so its efficiency is very high.
Power electronic converter systems are highly reliable.
Since there is no moving parts in power electronic systems so it has long life and also its maintenance cost is very less.
The power electronic systems has fast dynamic response in comparison to electromechanical converter systems.
Since the power electronic system has small size and also it has less weight so they occupy less floor space and hence their installation cost is also less.
Now these days power equipments are being mostly used, so power semiconductor devices are being produced on a large scale, resulting in lower cost of converter equipment.
Power electronics are used in computer and office equipments.
It is used in uninterruptible power supplies.
Power electronics are used in elevators.
Power electronics is also used in light dimmers and flashers

The power electronic converter circuits have a tendency to generate harmonics in the supply system as well as in the load circuit.
AC to DC and DC to AC converters operate at a low input power factor under certain operating conditions. In order to avoid a low power factor, some special measures have to be adopted.
The overload capacity of power electronic controllers are very low.
It is very difficult to regenerate power in power electronic converter systems.
