Whether indoors or outdoors this high-efficiency inverter can provide clean AC to power all your small appliances like fans, lights, soldering irons, etc.
Making a low cost, simple 50 watt inverter
An inverter can be taken as a crude form of UPS. Obviously the main use of an inverter is only for powering common electrical appliances like lights and fans during a power failure.

As the name suggests the basic function of an inverter is to invert an input direct voltage (12VDC) into a much larger magnitude of alternating voltage (generally 110VAC or 220VAC).
Before learning how tobuild an inverter, let’s first understand the following fundamental elements of an inverter and its operating principle:
Oscillator: Anoscillator converts the input DC (Direct Current) from a lead acid battery into an oscillating current or a square wave which is fed to the secondary winding of a power transformer. In the present circuit, IC 4049 has been used for the oscillator section.
Transformer: Here the applied oscillating voltage is stepped up as per the ratio of the windings of the transformer and an AC much higher than the input DC source becomes available at the primary winding or the output of the inverter.
