The Controlled Voltage Single Input Multiple Output DC to DC Converter proposes a design of highly efficient coupled inductor single input multiple output (SIMO) dc to dc converter. The converter can boost a low voltage input power source to a controllable high voltage dc bus and middle voltage output terminals. The controllable high voltage dc bus acts as the main power supply for the high voltage dc load. Moreover the middle voltage output terminals can supply powers for charging auxiliary power sources (e.g., battery modules). The Proposed circuit was simulated in PSIM with input voltage of 12 V; the corresponding output voltages obtained are 24V and 200V respectively. The desired theoretical voltage wave forms are obtained using PSIM. Also the controlled output voltage design of the proposed converter is implemented by using a PI controller and the circuit is verified using PSIM.
