Normally a single-phase voltage varies through analog strategies which include a dimmer however we can't get precise voltage through a dimmer also. To acquire a smart/precise voltage stage VFD drives are used. To range voltage by converting the firing perspective of the Thyristor a variable ac voltage may be obtained. Thyristor conducts in both cycles of ac. If conduction perspective is managed through the firing perspective of the Thyristor. For 1/2 of ac cycle firing perspective modifications from zero degrees to one hundred eighty degrees in accordance to that conduction perspective modifications. As conduction perspective and firing perspective are inversely proportional to every other. Means that if firing perspective much less then conduction perspective is greater and vice versa. A 0 crossing detector circuit is used to know the 0 crossing of ac voltage. While 0 crossing phase offers output of common sense 1 then from this factor ac voltage begins to rise/fall. This is the reference factor from that factor to most one hundred eighty degree factor firing perspective may be managed. In this manner a variable output voltage is generated.

“…This can be achieved from a single source through use of H-bridge inverter circuit in Figure 1. In standard Hbridge circuit switch S1(MOSFET 1), S3(MOSFET 3), S2(MOSFET 2), and S4(MOSFET) are arranged in this configuration [2]. Both gating signal Gs1(gate MOSFET 1) and Gs4(gate MOSFET 4) are switched simultaneously at one half of a cycle while both gating signals Gs2(gate MOSFET 2) and Gs3(gate MOSFET 3) are simultaneous switch at the other half [3] [4].…”

Photovoltaic is use to supply electricity from sunlight. Inverter is used to convert the direct current (DC) from photovoltaic to alternating current (AC). This project is to design and develop a single phase inverter that able to invert the input voltage of DC to output voltage of AC using PROTEUS software. The inverter based on 8 bits for one cycle of a driver pulse wave. This simulation used before doing the hardware. This software can save a lot of time on this exact simulation of the prototype.

Over the years, access control systems have become more and more sophisticated and several security measures have been employed to combat the menace of insecurity of lives and property. This is done by preventing unauthorized entrance into buildings through entrance doors using conventional and electronic locks, discrete access code, and biometric methods such as the finger prints, thumb prints, the iris and facial recognition. We have designed a flexible and low cost modular system based on integration of keypad, magnetic lock and a controller. PIC 16F876A which is an 8-bit Microcontroller, is used here as a main controller. An advanced simulation based compiler Flowcode V4 is used to develop the software part in this project.Comment: ISSN: 1839-517
