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.
