PISB Control of Single Phase Quasi Impedance Source DC-DC Converter

The objective of the proposed topology for buck boosts energy conversion with a reduced ripple in the output voltage and current. The proposed topology contains quasi impedance source network which has one diode, two capacitors, two inductors are used to maintain continues current on the primary side by implementing simple boost PWM technique with PI controller. By PISB (Proportional Integral Simple Boost) control method, the proposed DC-DC converter gets high efficiency, nearly twofold increased gain, over twofold boost factor and reduced ripple in the output voltage compared with the conventional method.
