| Abstract |
This work contains general and concrete statements concerning the selection and comparison of power electronic devices. As an example we have considered a DC-chopper for motor control in which BJTs, darlingtons, MOSFETs and GTOs are investigated and compared. All these devices are easily applicable within the range of 1 kHz. In the range of more than 5 kHz the unsnubbered darlington and the GTO cannot be used because the power loss will increase rapidly. At 100kHz the power-MOSFET is the best. The BJT is also applicable if it works at smaller currents. The main advantages of GTOs and MOSFETs are the high voltage stress and the very small drive power respectively. |
