Implementation of Multiple Output Converters using Time Division Multiple Control with Soft switching and EMI Filter

Multiple output converters (MOCs) are widely used in equipment for industrial, commercial, and military application like the voltage regulator modules in portable electronic devices.They are preferred due to their advantages in cost, volume, and efficiency.However, most of the MOCs developed so far have limitations in terms of the number of outputs, the tight regulation of all the outputs and the ease of control.In this letter, a novel time division multiple control (TDMC) method which can regulate all of the outputs with high precision is proposed.The proposed charger is able to charge three different kinds of batteries in different state of charges (SOCs) independently and accurately with the constant current/constant voltage (CC/CV) charge method.Also it can offer a high efficiency due to the available soft switching condition at all the switches and EMI filter for reduction of unwanted harmonics.
