Application specific integrated circuit for controlling power devices for commutating a motor based on the back emf of motor

摘要: A motor for use with a power supply comprising stator, rotor in magnetic coupling relation to the plurality of insulated gate bipolar transistors (IGBTs), user interface, microcontroller and an application specific integrated circuit (ASIC). Each IGBT has control input port is connected between stator selectively applying response signal applied port. The interface provides signals indicative one or more desired operating parameters motor. inputs receiving low voltage output ports providing commutating as function signals. ASIC high IGBTs. via its which correspond provided by microcontroller. commutation based on zero crossing intervals, pulse current regulation dynamic braking. includes bidirectional state machine reset event that switches below minimum.
