An Intelligent Power Module With Switch Mode Rectifier Based Charger

A switch-mode rectifier (SMR) can provide adjustable and well-regulated DC output voltage from the available AC source with good line drawn power quality. This research introduces a novel Buck-Boost converter that incorporates Zero Voltage Transition (ZVT) and Zero Current Transition (ZCT) techniques, and its practical application as an emergency adapter. The system produces a reliable 230V/50Hz emergency output using automotive batteries and various household or commercial appliance batteries, necessitating an inverter following a boost converter for this purpose. In buck converter mode, a rectifier and buck converter are used to charge the batteries after receiving 12V from the grid. The adapter produces excellent output AC voltage sine waves. In a boost converter, soft switching is used to operate the semiconductor switches. Zero Voltage Transition (ZVT) turns the converter ON, while Zero Current Transition (ZCT) shuts it OFF. The remarkable versatility and high efficiency of the Buck-Boost converter position it as a promising solution not only for emergency power applications but also for a wide array of other scenarios.
