Devices used in electric vehicles consist mostly of dc/dc converters for battery charging and dc/ac converters to power the propulsion motor. Electric trains use power electronic devices to obtain power, as well as for vector control using pulse-width modulation (PWM) rectifiers. The trains obtain their power from power lines.
Electronic devices are a specialized kind of electrical devices in which electric power is predominantly used for data processing rather than the generation of mechanical forces. To better differentiate between both classes, electric devices that emphasize physical work are also called electromechanical.
A power capacitor intended to be used in power electronic equipment and capable of operating continuously under non-sinusoidal current or voltage. power electronics The field of electronics which deals with the conversion or switching of electric power with or without control of that power. principal arm
A device used to increase voltage on an electric power distribution system, such as a motor-generator set on a DC system. bound charge Electric charge in a material that is not free to move through the material. braking chopper A device used to absorb energy from a motor to slow it down. branch circuit
The power MOSFET is the most common power device in the world, due to its low gate drive power, fast switching speed, and advanced paralleling capability. [16] It has a wide range of power electronic applications, such as portable information appliances , power integrated circuits, cell phones , notebook computers , and the communications ...
Power MOSFETs are commonly used in automotive electronics, particularly as switching devices in electronic control units, [93] and as power converters in modern electric vehicles. [94] The insulated-gate bipolar transistor (IGBT), a hybrid MOS-bipolar transistor, is also used for a wide variety of applications.
Most electrical connectors have a gender – i.e. the male component, called a plug, connects to the female component, or socket. Thousands of configurations of connectors are manufactured for power, data, and audiovisual applications. [3] Electrical connectors can be divided into four basic categories, differentiated by their function: [4]
Power management ICs are solid-state devices that control the flow and direction of electrical power. Many electrical devices use multiple internal voltages (e.g., 5 V, 3.3 V, 1.8 V, etc.) and sources of external power (e.g., wall outlet, battery, etc.), meaning that the power design of the device has multiple requirements for operation. A PMIC ...
