Abstract :
The development of a rechargeable portable power supply is presented. A novel topology is proposed which combines the function of rectifier, inverter, step-up and step-down converter into a single circuit, reducing components used, resulting in a unit that is compact, lightweight, reliable, and cheap. The concept of a variable voltage DC link between the power conversion stages and a new inverter switching scheme have been proposed and realized. The concepts presented have been amply verified and are also applicable to uninterruptible power supplies and stand-by power systems
