| Abstract |
This paper deals with the control of the voltage of the capacitors in a 5-level flying capacitor converter. This type of converter takes advantage of the series connection of low voltage power semiconductor devices in order to handle high voltages. Its key feature is the utilisation of clamping capacitors in order to equally split the total volateb between the power semiconductor devices and at the same time having at the output several voltage levels. However, keeping the capacitor voltages at their right values is a well-known constraint of this converter. In this paper we present a logic approach based on the redundancy of the switching states in order to balance the voltage of the capacitors in a 5-level flying capacitor converter. Simulation results are presented to demonstrate the validity of the balancing logic presented. |
