A power semiconductor device is a semiconductor device used as a switch or rectifier in power electronics (for example in a switch-mode power supply).Such a device is also called a power device or, when used in an integrated circuit, a power IC.. A power semiconductor device is usually used in "commutation mode" (i.e., it is either on or off), and therefore has a design . The voltage regulator compensates for the change in load. Commercial voltage regulators normally operate on a range of voltages, for example – V or 90– V. Voltage regulators are used in devices like air conditioners, refrigerators, televisions etc. in order to protect them from fluctuating input voltage. A voltage multiplier is an electrical circuit that converts AC electrical power from a lower voltage to a higher DC voltage, typically using a network of capacitors and diodes. Voltage multipliers can be used to generate a few volts for electronic appliances, to millions of volts for purposes such as high-energy physics experiments and lightning safety testing.   I had a problem for a while with optocoupler and triac interfaces. I was told that eventhough connecting the collector and emitter of the optocoupler to a V AC source, the voltage will never ever be V because of the breakdown voltage of the diac. What is the breakdown voltage exactly.

For example, high voltage circuits may require components that have higher breakdown voltage ratings and the capability to handle higher currents. Circuit optimization can protect those devices from inductive loads or any large stray inductance that can cause reverse voltages that damage the components.
