| Abstract: | The structure of IGBT high power module and the principle of chopper circuit are first introduced. Secondly methods of current balancing for paralleling IGBT power modules in a rectifier system are introduced. Finally some configurations are discussed, for example 6, 12 and 24 pulse rectifiers with multiple chopper loads, and high current and low voltages DC chopper rectifier systems. Advantages and benefits are given in the chopper rectifier system such as low output ripple, fast dynamic (response,) reduced flicker, high power factor, higher system efficiencies, and reduction in over all (system) volume and cost. |
