SPECIFICATIONS FOR TRANSFORMERS IN THE DESIGN OF A 5KVA PURE SINE WAVE POWER INVERTER

ABSTRACT

A transformer is a device that transforms electric energy from one alternating current circuit to one or more other circuits using electromagnetic induction. The process can involve either raising (stepping up) or lowering (stepping down) the voltage. The method includes a primary winding that creates a magnetic field inside a core, which then induces a voltage in a secondary winding. The primary winding generates a dynamic magnetic field as an electric current flows through it. The secondary winding then experiences an electric current due to this magnetic field. In this project, the transformer's main goal is to increase the input voltage, which raises the output voltage. Specifically, the primary winding is connected to an energy source of 21V, while the secondary winding is linked to the load. This configuration is anticipated to yield an output of 230V. Calculations were performed to determine the appropriate number of turns for both the primary and secondary windings, and it was determined that the primary winding should have 11 turns and the secondary winding should have 120 turns. The transformer was constructed using these specified values. The transformer was tested to evaluate how it would work under various loads. These tests revealed that the transformer's output produced a voltage of 230 Volts.
