Active control of flying capacitor currents in multilevel voltage-source inverters

Original language description

Analyzed is an output voltage generation technique in multilevel voltage-source inverters with flying capacitors (FLC VSI) utilizing SVM modulation that enables the limitation of voltage ripple across flying capacitors for small modulation depths. This may reduce the capacitance of flying caps in applications where high current overloads are demanded at low AC output voltages, e.g. at motor start. For small modulation depths, the so called zero-voltage vectors must be used in the SVM. the method is based on varying the time distribution of these vectors. By the change of this time distribution, an active control of the currents flowing through the flying capacitors is possible to some extent. The principle of this adaptation is explained, its proprtiesunder steady and transient states are discussed and practical results with 4-level 4 kVA FLC VSI are presented.
