Loss Minimized Pulse Width Modulation of IGBT Current Source Converters

The current source converter represents the dual counter part to the better known and more frequently used voltage source converter. As such due to duality rules many off-the-shelf solutions concerning the VSC can be used in a modified manner to handle the CSC. This work gives a comprehensive overview of IGBT CSC PWM methods and shows how they are to be distinguished. Then based on duality considerations a complete recipe is given on how to utilize usual micro controller peripherals along with some logic elements to achieve the most significant PWM methods with little effort
