Simple boost converter using Timer IC 555 for charging capacitor banks

Abstract

A boost converter is capable to increase input voltage to a certain voltage level which is required by a high voltage load. In this project, a 12V battery is used as input voltage to the boost converter circuit. The Timer IC 555 is the main control device used to control the switching of the MOSFET. The main objectives of this project are to study and design a simple, portable, and low cost boost converter for charging capacitor banks.

“…The clock is an essential timing instrument setting up a timing sequence within the circuit to control the on/off times of the circuit [13,14].…”

“…In other words the decision circuit performs the task of switching the load to an on or off status depending on what the previous status of the load was. The utilized clock circuit is arranged from a 555 timer monostable circuit [14,18] which is triggered by the control signal from the ring detector circuit. The designed clock circuitry is shown in Fig.…”
