Power Inverters – How They Work and Their Applications
The power inverter is a device that converts the direct current into alternating current. Most often, an inverter is used to transform the voltage from a car battery with a size of 12VDC or 24VDC to 220VAC, suitable for powering a variety of devices.
The basic principle of operation is the alternative switching (by means of powerful transistors or thyristors) of constant voltage to the windings of a transformer, which supplies the output with the alternating voltage of the required size.
The power inverter is a combined device with several built-in protections that protect the devices connected to it from high voltage, overload, and short circuit. Some of the power inverters available have a built-in charger. They can be used to recharge a variety of different types of rechargeable batteries and uninterruptible power supplies (UPS) for:
fireplaces with water jackets
Also, for any other devices, where loss of power would lead to severe accidents or data loss.
Car Inverters and RV Inverters
The power inverter is widely used as a power supply for a car, truck, bus, RV, camper or yacht, for a number of electrical devices operating at 220 V such as:
