| A power inverter is an electronic circuit that converts direct current (DC) to alternating current (AC). Inverters are used in a wide range of applications, from small switching power supplies in computers, to large electric utility applications that transport bulk power. The inverter is so named because it performs the opposite function of a rectifier.
Some of the popular applications of power inverters are:
• DC power source utilization - An inverter allows the 12 or 24 volt (battery) DC power available in an automobile or from solar panels to supply AC power to operate equipment.
• Uninterruptible power supplies - One type of uninterruptible power supply uses batteries to store power and an inverter to supply AC power from the batteries when main power is not available. When main power is restored, a rectifier is used to supply DC power to recharge the batteries
Buying Power Inverters
You can find a wide range of Power Inverters to meet your specific applications. While choosing a Power Inverter, you should consider the following:
• Total wattage of connected devices should not exceed the model's continuous wattage rating
• Number of connected items of equipment to determine how many outlets are required
• Application to help you choose the proper type of inverter or inverter/charger
Power Inverters Working
The functioning of a power inverter is very simple. In one simple inverter circuit, DC power is connected to a transformer through the centre tap of the primary winding. A switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary winding and then the other. The alternation of the direction of current in the primary winding of the transformer produces alternating current (AC) in the secondary circuit.
Power Inverters Brands
Despite of many power inverters in the market, it is usually recommended to go with a company well known for the specific tool that you are purchasing. Here are the companies that are considered name brands of power inverters, including Coleman, Black And Decker, Xantrex, Cobra, Vector and many more.
