Fremont, CA: Power electronics has witnessed significant demand growth in recent years, and power electronic devices are now available in almost all applications. As a result, it's critical to research the benefits of these devices that have made them famous. The following are some of the benefits and drawbacks of power electronic converters:
Advantages of Power Electronic Converters
Mass Production: Due to significant advancements in semiconductor device manufacturing techniques, these semiconductor-based power electronic devices are now mass-produced in large quantities, resulting in low prices. There is a range of voltage level to choose from with these instruments.
Highly Reliable: Since these devices do not have mechanical moving parts, they have a shallow risk of failure and, as a result, have a very robust performance and long life if using it under high - efficiency.
Highly Efficient: In most applications, these devices operate as a switch, and many know that the power loss in both modes of the control, i.e. ON and OFF, is very minimal, as well as the switching losses.
Negligible Maintenance: Power electronic systems need almost no maintenance due to the lack of mechanical moving parts.
Fast: Power electronic systems have a much quicker dynamic response than mechanical or electromechanical devices.
Size:Compared to mechanical systems with equivalent power ratings, these power electronic systems are much smaller in size, resulting in less weight, less floor space, fewer handling problems, lower construction costs, lower packaging and shipping costs, and so on.
Disadvantages of Power Electronic Converters
Harmonics: One of the severe drawbacks of power electronic systems was whether they introduce significant harmonics on sides, the linked load side and the power source side. Harmonics are induced in the converter's output voltage, current and the converter's input current since the converters change the sinusoidal waveform according to the requirements.These harmonics are now causing a lot of problems on both sides. Harmonics cause issues on the load side, such as excessive heating, increased acoustic noise, torque vibration of a motor shaft, commutation issues in DC motors, and so on.
Low Power Factor: Since some power, electronic converters have an external input power factor, shunt compensation equipment may be necessary.
Low Overload Capacity: When a proper heat evacuation system is in place, power electronic devices operate at rated voltage and current. Hot spots at junctions and system burning are possible due to excessive current.Power electronics has seen a considerable increase in demand in recent years, and they are available in all applications.
