Rechargeable batteries are now widely used in many applications. The bidirectional adapter having the function of charging and discharging provides 230 V/50 Hz emergency output form the battery embedded in a UPS, Electrical Vehicles and other possible appliances. This bidirectional adapter having the function of for the forward mode providing the AC power and reverse mode providing a DC power from the battery to the critical power appliances. In forward mode, a front end DC/DC converter is equipped to establish a boosted DC link voltage from battery. This DC is inverted into emergency source for critical power appliances using H-Bridge converter. The output AC sinusoidal voltage obtained with inverter circuit. Conversely in charging mode, a Switch Mode Rectifier (SMR) based charger is formed using Intelligent Power Module. The two power stages are implemented using Intelligent Power Module. This Intelligent Power Module consists of one converter module and inverter module. In the proposed power module, the design and implementation of switch mode rectifier (SMR) based bidirectional laptop adapter is being simulated and the result are being presented [1, 2]. © Springer India 2015.
