Power electronics deals with the devices that can convert and control the power from source to load in an efficient manner. Power electronic devices are used in order to prevent damage caused by fluctuating current and high voltages. There are different type of power electronics devices used like Power IC, Power Module, and Power Discrete. Power electronics have numerous applications in consumer electronics and Energy & power industry.
Power electronics is a solid-state circuitry device that converts and controls electric power from the source to the load in an efficient and convenient manner. It is used to control the fluctuated power from one device to other power devices such as diodes, transistors, and thyristors. It enables power management to enhance energy conservation in various applications such as industrial systems, consumer electronic, and electric vehicles. In addition, power electronics can control the flow of energy in unidirectional as well as bidirectional manner, depending upon the usage. Currently, it is used in renewable resources and electric vehicles to improve switching speed and prevent power loss.
