Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves . In modern systems, the conversion is performed with semiconductor switching devices such as diodes , thyristors , and power transistors such as the power MOSFET and IGBT .
Power modules are used for power conversion equipment such as industrial motor drives, embedded motor drives, uninterruptible power supplies, AC-DC power supplies and in welder power supplies. Power modules are also widely found in inverters for renewable energies as wind turbines, solar power panels, tidal power plants and electric vehicles (EVs).
This is a list of U.S. states by electricity production.The US generated 4,231 TWh in 2022. Some 41 TWh of net imports and 204 TWh of line losses resulted in total consumption of 4,067 TWh. [1]
The power MOSFET, which is commonly used in power electronics, was developed in the early 1970s. [84] The power MOSFET enables low gate drive power, fast switching speed, and advanced paralleling capability. [85] The power MOSFET is the most widely used power device in the world. [85]
It is used in switching power supplies in high-power applications: variable-frequency drives (VFDs) for motor control in electric cars, trains, variable-speed refrigerators, and air conditioners, as well as lamp ballasts, arc-welding machines, photovoltaic and hybrid inverters, uninterruptible power supply systems (UPS), and induction stoves.
The VFD controller is a solid-state power electronics conversion system consisting of three distinct sub-systems: a rectifier bridge converter, a direct current (DC) link, and an inverter. Voltage-source inverter (VSI) drives (see 'Generic topologies' sub-section below) are by far the most common type of drives.
