Below are some of the key advantages and disadvantages of power electronic converters: The Advantages of Power Electronics Mass Production Technological developments in semiconductor manufacturing have led to the widespread and economical availability of power electronic devices. Because these devices are available at different voltage and current levels, several options are available. Highly Reliable When used under rated settings, these devices' robust, long-lasting performance and lack of mechanical moving components lead to fewer failures. Highly Efficient These devices function as switches in most applications, and we know that switches have very low power loss and switching losses in both ON and OFF modes. Negligible Maintenance Almost no maintenance is needed for the power electronic systems because they do not have any mechanical moving parts. Fast The dynamic response of power electronic systems is significantly faster than that of mechanical or electro-mechanical equipment. Size Compared to mechanical systems with comparable power ratings, these power electronic systems are much smaller, meaning they weigh less, take up less floor space, are easier to handle, require less installation, cost less to pack and ship, and have many other benefits. The Disadvantages of Power Electronics Harmonics Power electronic systems have only one significant drawback: they introduce significant harmonics to the power supply and associated load sides. The output voltage and current of the converters and the input current produce harmonics since they modify the sinusoidal waveform to meet the requirements. Both sides are now having a lot of problems because of these harmonics. If we have motors, harmonics on the load side lead to concerns like excessive heating, increased acoustic noise, torsional vibration of the motor shaft, malfunctions with DC motor commutation, etc. Therefore, modern VFD motors are specifically made to withstand the impacts of harmonics better. In addition, we offer filter circuits that limit the load's harmonics. Harmonics also cause a great deal of difficulties on the supply side. There is a significant impact on the functionality of other devices connected to the same source. Additionally, supply line harmonics cause radio interference with audio and video equipment and communication lines. In addition to this, the input side transformer overheats and loses efficiency. Special converter transformers are employed when the output of electronic devices, like industrial motor drives, has a significant amount of power. Low Power Factor Reactive power adjustment equipment must be installed because some power electronic converters have low input power factors. Low Overload Capacity Power electronic devices must stay within their rated current and voltage ranges. Excessive current can cause device failure and overheating. Protection measures like snubber circuits are crucial to avoid problems like incorrect triggering. ...Read more
