摘要： PROBLEM TO BE SOLVED: To provide a motor controller by which the number of current detecting means is suppressed, and all the phase currents are continuously detected even when one of the phase currents detected by the current detecting means becomes abnormal. SOLUTION: The motor controller includes: a power conversion circuit 11; current sensors 13 to 15; and a control circuit 16. The current sensors 13 to 15 are provided one by one for each phase. A control circuit 16 controls a power conversion circuit 11 based on detection results of the current sensors 13 to 15. When one phase current out of the phase currents detected by the current sensors 13 to 15 is abnormal, the phase current corresponding to an abnormal phase is obtained from a normally detected phase current. Then, the power conversion circuit 11 is controlled based on the normally detected phase current and the obtained phase current. As a result, the number of the current sensors is suppressed from the conventional required four units to three units, and all the phase currents are continuously detected even when one of the phase currents detected by the current sensors 13 to 15 becomes abnormal.

摘要： PROBLEM TO BE SOLVED: To solve the problem of inconvenience which occurs by deciding whether overcurrent flows between the input/output terminals of a switching element by using a digital circuit. SOLUTION: The current flowing between the collector and the emitter of a switching element SW is detected indirectly as a voltage drop amount, caused by a minute current outputted from a sense terminal ST, and is applied to an inversion input terminal of a comparator 30. The temperature of the switching element SW is detected by a thermosensitive diode D. The output of the thermosensitive diode D is converted by an output conversion circuit 50. As a result of this, output signal Vo is such a signal that corresponds to the threshold, in deciding whether the current, flowing between the collector and the emitter of the switching element SW, is equal to or higher than the threshold. This output signal Vo is applied to a non-inversion input terminal of the comparator 30. COPYRIGHT: (C)2008,JPO&INPIT
