Improvise Dc to Ac Inverter

Chapter I I. Introduction Power electronics converters can be found wherever there is a need to change voltage, current of frequency of electric power. The power range of these converters is forming some mill watts (as in mobile phone) to thousands of megawatts in an HVDC transmission system. With classical electronics, electrical currents, and voltage are used to carry information, where as with power electronics, they carry power electronics becomes the efficiency An inverter converts DC to AC, and also changes voltages. In other words, it is a power adopter. It allows a battery – based system to run conversional AC appliances director through conventional home wiring. There are ways to use DC directly, but for a modern lifestyle you will need an inverter for the vast majority if not all your loads in electrical terms loads are devices that use electrical energy.

Power inverter A power inverter, or inverter, is an electrical power converter that changes direct current (DC) to alternating current AC) the converted AC can bet any required voltage and frequency with the use of appropriate transformer switching and control circuits. II. Title of the study

III. Statement of the problem

IV. Theoretical framework

V. Scope and limitation
DC- AC inverter only design for the purpose of emergency. If inverts 12v D>C to 220 volts AC. It is capable of inverting voltage can be used in emergency operation. It can only operate to incandescent lamp, electric fan for the emergency use.

VI. Significance of the study This significance of the study is stated as follows: 1. The students will study to lead to an improved implementation of the electrical curriculum since the study focuses on the variables contributory to the implementation of this program. 2. The faculty needs of the teacher respondents will be discovered and based on the findings, this development programs can be designed to address teachers needs. 3.
