Pulse Width Modulation for Current Source Converters – A Detailed Concept
نویسندگان
چکیده
Abstract – 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 offthe-shelf solutions concerning the VSC can be used in a modified manner to handle the CSC. This work gives a comprehensive overview of CSC PWM methods and shows how they are to be distinguished. Then based on duality considerations a complete recipe is given on how to utilise usual micro controller peripherals along with some logic elements to achieve the most significant PWM methods with little effort.
