A Multi-Input Switched Capacitor Bidirectional DC-DC Converter with Triple Closed Loop Control for Electric Vehicle Application

Multi input system is best suitable for uninter-rupted power supply (UPS) applications. Moreover, it provides increased mileage for electric vehicle applications. Multi input bidirectional switched capacitor (MIBSC) DC-DC converter with reduced number of components for above applications are implemented in this paper. The MIBSC DC-DC converter has the following advantages: a) multi input with reduced number of inductors, b) minimum number of components compared to conventional topologies, c) high voltage gain ratio. d) reduced design complexity. e) synchronous rectification with increased performance f) triple closed loop control with increased system stability g) reduced voltage stress in switches. A 780W system is implemented in software (MATLAB/Simulink).
