High voltage transistors have several advantages in different applications with a focus made in power electronics and high power applications.
Here are some of the key advantages:
- The high voltage transistor is capable of dealing with powerful interfering signals of high current and therefore useful in power supplies such as motor control, and amplifiers supplies.
- Such transistors may provide high switching speeds which is important in switching frequency applications such as Switch Mode Power Supplies (SMPS) and Pulse Width Modulation (PWM) controllers.
- High voltage transistors may also be made to operate at a higher temperature, thus improving their reliability under high power conditions, as well as the lifetime of the various high power electronic devices.
- Employing high voltage transistors can help in a reduction of the number of circuit components, where usual voltage step down or step up stages usually requires.
- These transistors can work at either low or high voltage levels as is common with many applications where on gets to deal with levels of voltages in storage and use.
- These transistors are used in power electronic systems owing to their ability to work even at high voltages with low losses.
- If very high voltage transistors are used, then the size of the circuit may be reduced as the need for extra components such as transformers or inductors for voltage control may be eliminated.
- High voltage transistors have many of the components such as overvoltage protection incorporated and it is able to resist higher level of stress compared to normal transistors and thus increases safety on the system.
- They are designed to operate in critical areas where they can withstand common probe such as areas with high EMI or high temperatures as found in industries.
- High voltage transistors offer more design freedom to designers making circuits that require other voltages, thus are more versatile.
