Stages of an Inverter
As its name suggests DC to AC inverter is an electronic device that is capable of converting a DC potential normally derived from a lead-acid battery into an increased AC potential which can be very comparable to the voltage found in our domestic AC outlets .
Repairing sophisticated investors is not easy because of their many complex stages involved and require expertise in the field. Inverters that provide sine wave output or those that use PWM technology to generate modified sine wave can be difficult to diagnose and troubleshoot for people who are relatively new to electronics.
However, simpler inverter designs involving basic operating principles can be repaired even by a person who is not specifically an expert with electronics.
Before moving on to breakdown details, it would be important to discuss how an investor works and the different stages normally an investor can understand:
An investor in its most basic form can be divided into three fundamental stages to know. oscillator, conductor and transformer output stage.
Oscillator: This stage is basically responsible for the generation of oscillating pulses either through an IC circuit or a transistor circuit.
These oscillations are basically the productions of alternating positive and negative (earth) voltage peaks of the battery with a specified specific frequency (number of positive peaks per second). Such oscillations are generally in the form of square pillars and are referred to as square waves and the inverters operating with such oscillators are called square wave inverters.
The square wave pulses generated above are too weak and can never be used to drive high current output transformers. Therefore, these pulses are fed to the next stage of the amplifier for the required task.
