The main objective of this paper is to achieve a feedback enabled multi output boost converter (MOBC) by combining power electronics and process control concepts. A multi output boost converter produces multiple outputs from a single input. It provides two or more output voltages from a single input voltage. The implementation of feedback enabled MOBC comprises of basic MOBC unit, two comparators and a PI Controller. The PI (Proportional-Integral) controller here as such controls MOBC output based on its error input obtained as a result of comparison of MOBC output and setpoint. The use of electronic PI controller contributes to better stability of output and acts as a corrective mechanism to the MOBC.

Abstract


The main objective of this paper is to achieve a feedback enabled multi output boost converter (MOBC) by combining power electronics and process control concepts. A multi output boost converter produces multiple outputs from a single input. It provides two or more output voltages from a single input voltage. The implementation of feedback enabled MOBC comprises of basic MOBC unit, two comparators and a PI Controller. The PI (Proportional-Integral) controller here as such controls MOBC output based on its error input obtained as a result of comparison of MOBC output and setpoint. The use of electronic PI controller contributes to better stability of output and acts as a corrective mechanism to the MOBC.
