21. The implementation using NPN type bipolar transistor is based on example from popular electronics hobby magazine. 22. Examples include p n diodes and bipolar transistors . 23. Bipolar transistor -based logic ( such as TTL ) does not have such a high fanout capacity.24. By comparison, in most bipolar transistors the size of the device does not significantly affect its performance. 25. The 1995 stock uses Alstom's " Onix " three-phase Insulated Gate Bipolar Transistor ( IGBT ) drive. 26. According to the rectified when it flows through the base / emitter junction of a bipolar transistor . 27. Providing sufficient base drive current is a key problem in the use of bipolar transistors as switches. 28. The " gain " of a bipolar transistor normally refers to forward current transfer ratio, either " h" 29. As with all " Electrostar " units, they use insulated-gate bipolar transistor ( IGBT ) AC motor drives. 30. This device allows operation at higher frequencies than a bipolar transistor , but is limited to low voltage applications.
