This voltage is finally utilized for powering the various household electrical gadgets like lights, fans, mixers, soldering irons etc. here the low level AC from the above discussed electronic stages is applied to the secondary windings resulting in an induced stepped up voltage across the primary winding of the transformer. In inverters a transformer is used for similar purpose but with just opposite orientation, i.e. We all know how a transformer works in AC/DC power supplies it is normally used to step-down the applied input mains AC to the lower specified AC levels through magnetic induction of its two windings. The amplified voltage is therefore finally applied to the output transformer secondary winding. Though the boosted response is an AC, it is still at the battery supply voltage level and therefore cannot be used to operate electrical appliances which work at higher voltage AC potentials. Here the received oscillating frequency is suitably amplified to high current levels using either power transistors or Mosfets.

Therefore these pulses are fed to the next amplifier stage for the required task.įor info on Inverter oscillators you can also refer to the complete tutorial which explains how to design an Inverter from the scratch Booster or Amplifier (Driver):
The above generated square wave pulses though are too weak and can never be utilized to drive high current output transformers.
These oscillations are basically the productions of alternate battery positive and negative (ground) voltage peaks with a particular specified frequency (number of positive peaks per second.) Such oscillations are generally in the form of square pillars and are termed as square waves, and the inverters operating with such oscillators are called square wave inverters. This stage is basically responsible for the generation of oscillating pulses either through an IC circuit or a transistorized circuit.

oscillator, driver and the transformer output stage. However, simpler inverter designs that involve basic operating principles can be repaired even by a person who is not specifically an expert with electronics.īefore we move into the fault finding details it would be important to discuss how does an inverter work and the different stages normally an inverter may comprise:Īn inverter in its most basic form may be divided into three fundamental stages viz. Inverters which provide sine wave outputs or the ones which use PWM technology to generate modified sine wave can be difficult to diagnose and troubleshoot for the folks who are relatively new to electronics. Repairing sophisticated inverters are not easy due to their many involved complex stages and requires expertise in the field. The output from an inverter are normally quite comparable to the voltage that is found in our domestic AC Mains outlets. Stages of an InverterĪs the name suggests DC to AC inverter is an electronic device which is able to "invert" a DC potential normally derived from a lead-acid battery into a stepped-up AC potential. The following content explains regarding the important aspects of an inverter. Before we discuss how to repair an inverter it would be important for you to first get fully informed regarding the basic functioning of an inverter and its stages.
