This project would increase the knowledge on power inverter application by constructing a 12V DC to 220V AC with output power rating at 600VA with frequency varying between 49.95Hz, which is approximately 50 Hz. The 600VA DC-AC power inverter is designed to produce backup power that runs on 12V DC batteries which are ecofriendly to produce backup power for a longer period of time. This makes it quite unaffordable by people with low income. The cost of maintenance turns to be expensive since they run on fuel, compared to an Inverter.

The carbon mono-oxide and the black oil from the generator pose threats to the environment as air and soil or water pollutant making it non-environmentally friendly. Some of the limitations of using generator as alternative or additional source of electricity are mostly noisy during its operation, which causes disturbances in the neighborhood. Even though all these backup supply systems turn to perform their said functions to some extent, they turn to pose some challenges. The most common backup supply systems available on the market are Automotive Generator Sets (convert mechanical energy to electrical energy by means of burning fossil fuel) and UPS (Uninterrupted power supply). Appendices provide information on transistor manufacture and parameters, and a new appendix on transistor letter symbols has been included.ABSTRACT In the light of prevailing power cuts in the country, there is a sudden rise of a need to come up with backup power solutions.

The plan of the book remains the same: semiconductor physics is introduced, followed by details of the design of transistors, amplifiers, receivers, oscillators and generators. New circuit techniques covered for the first time in this edition include current-dumping amplifiers, bridge output stages, dielectric resonator oscillators, crowbar protection circuits, thyristor field timebases, low-noise blocks and SHF amplifiers in satellite receivers, video clamps, picture enhancement circuits, motor drive circuits in video recorders and camcorders, and UHF modulators. Although integrated circuits have widespread application, the role of discrete transistors is undiminished, both as important building blocks which students must understand and as practical solutions to design problems, especially where appreciable power output or high voltage is required.

This seminal work has now been presented in a clear new format and completely updated to include the latest equipment such as laser diodes, Trapatt diodes, optocouplers and GaAs transistors, and the most recent line output stages and switch-mode power supplies. For over thirty years, Stan Amos has provided students and practitioners with a text they could rely on to keep them at the forefront of transistor circuit design.
