Power Electronics Converters: It's Advantages and Disadvantages

By Manufacturing Technology Insights | Monday, January 13, 2020

Some of the advantages of power electronic convertors include: reliability, efficiency, speed, maintenance, and size.

FREMONT, CA: Power Electronics has seen remarkable growth in recent times, and nearly all the applications now use power electronic devices in some or the other way. Therefore it becomes necessary for firms to study the benefits of these devices. Listed below are a few advantages and disadvantages of power electronic converters:

Advantages of Power Electronic Converters

Below are the advantages of power electric electronic converters:

• Mass Production: Due to the growth in the production methods of semiconductor devices, the semiconductor-based power electronic tools are now manufactured in bulk, therefore resulting in a low price. Besides, the devices are accessible in a range of current and voltage ratings to choose from.

• Highly Reliable: Since the devices have no mechanical moving components, there are very fewer failure chances. They also have a rugged performance and long life if operated under rated conditions.

• Very Efficient: In most applications, these devices act as a switch, and in both the modes of the switch, ON and OFF, the power loss in it is extremely less, and the switching losses are also low.

• Negligible Maintenance: Due to the absence of mechanical moving components, the power electronic systems need almost nil maintenance.

• Fast: Compared to electro-mechanical or mechanical devices, the power electronic systems have a faster dynamic response.

• Size: These power electronic systems are small in size when compared to mechanical systems for the same power ratings, therefore ensuing in less weight, floor space, handling issues, installation cost, packing and transportation prices, and others.

Disadvantages:

• Low Power Factor: Definite power electronic converters function at low input power factor, which might require installing reactive power compensation tools.

• Low Overload Capacity: Power electronic devices work on rated current and voltage provided proper heat evacuation system is offered. Excess current causes burning of devices and hot spots at junctions. High DV/DT leads to false triggering and hence a power electronic device will need protection arrangements like snubber circuit.
