In air conditioning, an inverter compressor is a compressor that is operated with an inverter.. In the hermetic type, it can either be a scroll or reciprocating compressor. ...
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. [2]
For example, in a refrigerator data such as temperature, humidity and motor speed are gathered through sensors to keep the motor running efficiently. Based on such data, a microcontroller optimizes performance. Motor speed is optimized and keeps the refrigerator’s temperature constant.
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.
Most refrigerators, air conditioners, pumps and industrial machinery use AC power, whereas most computers and digital equipment use DC power (digital devices plugged into the mains typically have an internal or external power adapter to convert from AC to DC power). AC power has the advantage of being easy to transform between voltages and is ...
Nowadays, it is used to power automotive accessories such as portable inverters, mobile phone chargers and portable refrigerators. These sockets were not originally designed to provide DC power, and are not an ideal DC connector for several reasons [citation needed], but still widely used for compatibility to existing accessories.
