| description | A compact DC-DC converter is required as an auxiliary power module in Electric Vehicles (EVs) to power the onboard electric motor and other auxiliaries. Most of the existing multi-port converters have limitations on duty ratio, charging currents of the inductor (<inline-formula> <tex-math notation="LaTeX">$\text{i}_{\mathrm {L1}}{>}\text{i}_{\mathrm {L2}}$ </tex-math></inline-formula> or <inline-formula> <tex-math notation="LaTeX">$\text{i}_{\mathrm {L1}}{< }\text {i}_{\mathrm {L2}}$ </tex-math></inline-formula>), output voltages (<inline-formula> <tex-math notation="LaTeX">$\text{V}_{01}{>}\text{V}_{02}$ </tex-math></inline-formula> or <inline-formula> <tex-math notation="LaTeX">$\text{V}_{01}{< }\text{V}_{02}$ </tex-math></inline-formula>), and the issue of cross-regulation during load variation. This paper presents a multi-port DC-DC converter with Single-Input Multiple-Output (SIMO) to circumvent all these limitations. The proposed topology generates independent outputs without affecting the other loads during the operation. It is observed that cross-regulation is effectively eliminated while controlling the loads. The control of the converter is simple without any duty ratio and inductor current charging constraints. The validity of the proposed converter has been verified by using a prototype with a 100W rating and delivers two output voltages of 24V and 14.4V at duty ratios of 50% and 30% with an input voltage of 48V. It can be extended to multiple outputs. The simulation and experimental results are analyzed to prove the effectiveness of this auxiliary power module for EV applications. |
