Senbaru‚ Nishihara-cho‚ Nakagami‚ Okinawa 903-0213‚ Japan Received 24 July 2000; accepted 9 January 2001 Abstract An extensive small-signal analysis of a voltage-mode controlled interleaved dual boost (IDB) converter operating in continuous current mode based on signal flow graph approach is proposed. Small-signal flow graph is developed‚ from which open-loop small-signal transfer functions are derived using well known Mason’s gain formula. Closed-loop small-signal input-to-output‚ control-to-output

CHAPTER 1 INTRODUCTION Now-a-days every institution needs automation. As a part of college automation‚ we have decided to do a project “voice interactive system for college automation”. Our project allows the user to know the student’s attendance and marks quickly through the telephone line without the intention of the college authority. In the hardware side embedded system has been used. The microcontroller controls the whole

electricity‚ and the greater your speed‚ the greater the voltage output. The cord from the generator leads first to the circuit board’s bridge rectifier‚ which converts the AC to DC. In other words‚ the up-and-down‚ positive-to-negative current becomes a steady positive current. Then‚ the capacitor levels out the DC voltage‚ producing a steady voltage inflow to the voltage regulator. The voltage regulator is crucial‚ as the phone only needs five volts to charge‚ whereas fast pedaling can produce 30 volts

interested me the most. I am amazed by the potential of power electronics in the field of Energy Systems. I decided to do my final year project in the field of Electronics. It involved designing of “Dual buck full bridge inverter with hysterisis current control”. It helped me in understanding the importance of simulating the electronic circuits on software like PSIM and MATLAB. It also gave me the opportunity to implement the design on physical hardware for the first time. Reading through the journals
