It is also used for induction heating because it converts the low-frequency power to high-frequency power. In an electric power system, the inverter feeds power to the distribution system. It is used for controlling the speed of the motor. The inverter supplying the AC to the electrical equipment when the power is not available. For improving the runtime of the inverter number of batteries are used for storing the DC power. If the number of devices using the inverter increases then their running time will decrease. Their runtime depends on the power of the battery.

The frequency of the output wave of the inverter remains same as that of the standard frequency, i.e., the 50 or 60 Hertz. The input voltage of the inverter is the constant DC power source, and their output may be square, sine or pulse sine wave depends on the circuit and design of the inverter. It does not generate electric power the power is supplied from the battery. The inverter is an electronic circuit that changes the DC to AC. In online double conversion UPS, the battery is always connected to the inverter due to which no additional power transfer switches require in the circuit. The line interruptive UPS has variable voltage transformer which adds or subtracts the power coils of wire. The line interruptive UPS is also known as the standby power system. The basic feature of the offline/standby inverter is to provide the backup power and protect the system from the power surges. The UPS is mainly categorised into three types. The UPS converts the AC to DC by the help of the rectifier and again converts the DC power into AC power by the help of an inverter. Their circuit consists the inverter, battery and the controller. The UPS has a battery which comes in contact with the power supply of the devices when it senses the power loss from the main supply. It also protects the system from power surges. The UPS allows the power to flow through the system so that the data can be saved before the primary supply is fully shut down. It is connected to the battery and appliances. Offline, Online, Line interruptive or Standby UPS. Main function is to convert AC power to DC power. The inverter converts the unidirectional current into bidirectional. The UPS is an electrical device that provides power to the load when the main power fails. During the power cut, the inverter receives the supply from the battery and provides the power supply to the electrical equipment. It takes the supply from the AC source and charges the battery. The inverter inverts the direct current to an alternating current. It provides the power for a short duration so that data can save before the complete shutdown of the system. The UPS has a battery which supplies the power during the power outages. The abbreviation of the UPS is the Uninterruptable Power Supply.
