摘要： While a PWM-controlled, FET-switched three-phase motor is operating in a mechanical damping mode, a single current sensor is used to measure current in the motor. When mechanical feedback into the motor exceeds a predetermined threshold, a bank of the FET switches can be closed to provide damping of the mechanical feedback. This causes currents to circulate within the motor, which an external single current sensor cannot measure to determine current load or when the mechanical feedback is no longer a problem. The present invention periodically switches selected switches necessary to sample the current in at least one phase of the motor to determine when the mechanical feedback into the motor is no longer a problem, while preferably also maintaining an average zero voltage vector.

摘要： A system and method for reducing torque ripple in a motor controller includes a step (60) of measuring an output voltage at each phase of the motor controller. A next step (61) includes determining a voltage mismatch between the phases. A next step (62) includes phase grounding one phase of the motor. A next step (63) includes calculating a voltage gain for the phases to compensate for voltage mismatches therebetween. The compensating gain can include a gain and/or offset, which are applied as a function of motor angle and is used to generate a PWM signal for driving the motor with reduced torque ripple.

摘要： Disclosed herein are a variety of different electrical system topologies intended to mitigate the impact of large intermittent loads on a 12 volt vehicle power distribution system. In some embodiments the intermittent load is disconnected from the remainder of the system and the voltage supplied to this load is allowed to fluctuate. In other embodiments, the voltage to critical loads is regulated independently of the voltage supplied to the remainder of the system. The different topologies described can be grouped into three categories, each corresponding to a different solution technique. One approach is to regulate the voltage to the critical loads. A second approach is to isolate the intermittent load that causes the drop in system voltage. The third approach is to use a different type of alternator that has a faster response than the conventional Lundell wound field machine.

摘要： A control module (100) includes a first signal processing unit (102) that is coupled to a second signal processing unit (114) by a control bus (130), an address bus (131) and a data bus (132). The control module conveys seed value addresses (108) and expected result addresses (110) over the address bus, seed values (118) and verification set output values (107) over the data bus, and compares each verification set output value to an expected result (120), thereby allowing the control module to determine whether the first signal processing unit, the control bus, the address bus, and the data bus are collectively functioning correctly. By properly selecting the seed value addresses, expected result addresses, seed values, and expected results (and correspondingly, verification set output values), proper operation of each line of the address bus and control bus may be individually verified.
