Abstract
A three-level boost converter uses a smaller inductor and lower voltage devices than the conventional boost converter. It has two capacitors connected in series across the output which leads to voltage imbalance problem due to mismatched capacitances. If not balanced, one of the capacitor voltages may be larger than the breakdown voltage of the switch, which would contribute to make damage to the switch. In this work the capacitor voltage imbalance problem has been studied for a three level boost converter. This capacitor voltage is balanced by the adopted control strategy by sensing the voltage across the two capacitors. The simulation of the voltage imbalance mitigation strategy is done by MATLAB/ Simulink.
