Realized Matrix Converter PWM Strategy for Hybrid Drive System
نویسنده
چکیده
Matrix converters have attracted an amount of interest over the past 25 years already, but they find time after time once again new utilisation. The presented paper deals with the recent concept of hybrid and power splitting traction drive systems. Special attention is paid to electric power splitting. In the investigated system a traction induction motor is employed. The matrix converter realised on the base of new progressive semiconductor elements is used to treat the electrically transmitted part of the whole drive energy. This solution is advantageous with regard to the reactive component reduction. The special digital control system consisting of two personal computers is used for the realised test bed. The matrix converter IGBTs are controlled by means of the designed indirect pulse width modulation method. Key-Words: Matrix converter, digital control system, PWM strategy, hybrid drive, electric power splitting, traction induction motor

Voltage Regulation of DC-DC Series Resonant Converter Operating in Discontinuous Conduction Mode: The Hybrid Control Approach
Dynamic modeling and control of dc-dc series resonant converter (SRC) especially when operating in discontinuous conduction mode (DCM) is still a challenge in power electronics. Due to semiconductors switching, SRC is naturally represented as a switched linear system, a class of hybrid systems. Nevertheless, the hybrid nature of the SRC is commonly neglected and it is modeled as a purely contin...
