The paper proposes a modified single-input double-output boost-flyback converter and its decoupling control technique. The converter avails two different outputs i.e. one to supply a light load at low-voltage and another to supply heavier load at higher voltage in single-stage itself. The availability of different voltage/power outputs is need of toady's automation in power applications such as in personal computers, electric vehicles, smart grids, shipboards. The major challenges of the coupled-inductor or flyback transformer-based multi-output converter are cross-coupling and cross-regulation issues. The proposed converter not only supplies two different outputs but also eliminate coupling and regulation issues. Moreover, the low voltage/power output of converter remains isolated from higher voltage/power output. The working principle of proposed converter and its PWM scheme, dynamic model and a procedure to find decoupling condition to design a decoupled control technique are discussed. Also, to verify the working of converter and its decoupled-control the simulation results are presented using MATLAB Simulink. |
