| Abstract: | The IGBT switched circuit used to conduct the direct current pulse width modulation control for the high power resistance strap was introduced, it can adjust the big and small of the load continuously in test. To avoid the temperature of the IGBT is high excessively, a unique double tube structure of the IGBT was adopted and the heat emitting system by double direct wind refrigeration by force was designed. The result indicate that the circuit is credibility and stably. |
