Jan 13, 2016 · Abstract Inverters are used in a large number of power applications. The function of an inverter is to convert DC power to AC, these are referred to as Voltage Source Inverters
Most inverters rely on resistors, capacitors, transistors, and other circuit devices for converting DC Voltage to AC Voltage. In alternating current, the current changes direction and flows forward and backward. The current whose direction changes periodically is called an alternating current (AC). It has non-zero frequency.
An inverter is an electrical device, which converts DC power to AC power and either increases or decreases the voltage level accordingly. In comparison, a converter changes the voltage level but does not change its type. So in converters, an AC voltage would still be AC and a DC voltage would still be in DC.
Basically, there are three techniques by which the voltage can be controlled in an inverter. They are, Internal control of Inverter. In this method of control, an ac voltage controller is connected at the output of the inverter to obtain the required (controlled) output ac voltage.
So in converters, an AC voltage would still be AC and a DC voltage would still be in DC. Inverters are becoming more popular along with along with solar power systems where we get a low voltage DC supply to power ordinary appliances that either run on 110V or 220V AC. Inverters are used in a large number of electrical power applications.
The inverting section absorbs power from the DC bus cap bank, inverts it back to simulated 3-Phase AC sine waves of varying voltage and varying frequency that are typically used to vary the speed of a 3-phase induction motor. The different steps to make a voltage inverter includes the following
The voltage inverter circuit is shown below, that uses a well known LM555IC timer chip. The schematic diagram divided into three parts, namely an oscillator, rectifier, and voltage regulator.An oscillator is used to convert DC into AC, a special type of rectifier is used to convert AC to DC and finally a voltage regulator.
