This paper proposes a single phase pulse-width modulated (PMW) voltage source uninterruptible power supply known as an improved standby boost uninterruptible power supply (ISBUPS) which centers on keeping the output voltage of the inverter system of the UPS at constant voltage of 220V AC and ripple free when utility power supply fails. This concept is achieved by incorporating proportional integral (PI) controller, boost converter and L-C filter at inverter control section. In this research, apart from stabilizing the inverter output voltage of inverter at 220VAC in standby mode, 0.96 modulation index is also realized. The total harmonic distortion of the system is reduced down to 5.05%. This proposed system has its applications at homes, offices and in business centers especially in Nigeria where electrical power instability is high now.
