Inverter technology helps in saving energy by eliminating wasted operations in home appliances by efficiently controlling motor speed. This is often used in producing appliances like washing machines, refrigerators, air conditioners, etc. It basically regulates the temperature of the appliances continuously and the inversion mechanism in it helps start off the appliances at a low power system.
An inverter is a voltage converter rectifier that converts DC current to AC current. The inverter technology is among the latest innovations of electro compressor motor technologies. The main objective of the inverter technology is to convert the voltage, optimise power transfer, grid synchronisation and storage interfacing by enabling batteries or other devices to store energy form distributed generator.
The technology saves power consumption by 20%-40% by controlling the appliance’s capacity to avoid irrelevant energy wastage. In comparison, a normal home appliance without inverter technology requires 3-4 times excess current to start, whereas appliances with inverter technology consist variable speed motors that require less current to start.
Usually, inverter compressor in the refrigerator or air conditioner compressor retain power depending on the temperature set on the thermostat and the incoming air. The inverter compressor helps in controlling the refrigerant flow rate.
When the appliance’s compressor works at peak load it tends to consume more power than the time when the load is less. This does not let the actual voltage of the appliance to fluctuate; instead, an inverter compressor uses its own energy to supply the set power to the appliances to provide stable energy. So, stabilised inverter helps in consuming less electricity.
Not just in refrigerators and ACs, but inverter technology is also present in washing machines. It helps the appliance in flexibly adjusting the rotation of the engine, which intends to improve the efficiency in washing the clothes, saving the water needed, and saving the electricity.
The regular motor faces rebates for higher power factors and a penalty for low power factor, whereas motors with inverter technology have a power factor close to unity. This helps to not only consume less electricity but also in getting rebates on better power factor.
Although expensive, inverter technology actually helps in saving electricity.
