Gan Kongyin Tang Baoyin Wang Xiaofeng Wang Langping Wang Songyan Wu Hongchen International Nuclear Information System (INIS) The simulation data using OrCAD are in accord with experimental results except the rise time It can output peak voltage 1.8 kV, rise time 300 ns, fall time 1.64 mu s waveforms on the loads. Experimental results show that IGBT solid state switch works very stable under the different conditions.
The static and dynamic balancing modules were carried out with metal oxide varistors, capacities and diodes in order to suppress the over-voltage during IGBT on and off. The experiments on the IGBT solid state switch for induction accelerator was carried out with two series 1.2 kV, 75 A IGBT (GA75TS120U).

The RC- IGBT traction converter system with gate pulse desaturated control is built, and the simulation and measurements show that the total losses of RC- IGBT with desaturated control decreased comparing to the RC- IGBT without desaturated control or conventional IGBT. Simulations and tests were carried out to consider the influence of total losses on the different amplitudes and durations of the desaturated pulse. The relationship among the gate desaturated pulse, conducting losses, and recovery losses is discussed. In this paper, a mathematic model is developed, referring to the datasheets and measurement data, to study the 6.5 kV/1000 A RC- IGBT switching features. In the same cooling conditions, RC- IGBT allows for a higher operating temperature.
Reverse Conducting IGBT (RC- IGBT constructs the conventional IGBT function and freewheel diode function in a single chip, which has a greater flow ability in the same package volume. Loss Characteristics of 6.5 kV RC- IGBT Applied to a Traction Converterĭirectory of Open Access Journals (Sweden)įull Text Available 6.5 kV level IGBT (Insulated Gate Bipolar Transistor modules are widely applied in megawatt locomotive (MCUs traction converters, to achieve an upper 3.5 kV DC link, which is beneficial for decreasing power losses and increasing the power density.
