摘要： A microcomputer that exercises driving control and power-generation control over a motor generator unit and a power-generation maintaining unit that, separately from the power-generation control exercised by the microcomputer, maintains a power-generation process performed by the motor generator unit are provided. While the microcomputer is operating normally, the power-generation maintaining unit allows the microcomputer to exercise the power-generation control. When an abnormality has occurred in the microcomputer, the power-generation maintaining unit acts as a backup or secondary controller to maintain the power-generation process performed by the motor generator unit, in an autonomous manner independently of the microcomputer.

摘要： An automotive rotary electrical apparatus with less than four switching control elements capable of blocking a field current while preventing breakage of the switching control elements in response to a malfunction in a feeder circuit for a field coil is proposed. First and second switching control elements controlled by first and second control signals, and first and second diode elements are used. The field control circuit switches the first control signal to the on-level signal while keeping the second control signal as the on-level signal, then switches the second control signal to the off-level signal while keeping the first control signal as the on-level signal, and further switches the first control signal to the off-level signal while keeping the second control signal to the off-level signal, when a short-to-power malfunction of the positive terminal or a short-circuit malfunction of the first switching control element occurs in the feeder circuit for the field coil.

摘要： The objective of the present invention is to obtain a vehicle electric-power conversion apparatus in which high-efficiency rectification operation can be realized, by detecting in real time a change, due to a fluctuation in a load, in a phase at which a switching element is turned on/off and by changing the phase at which the switching element is turned on/off, in response to the change. A diode-on timing and a diode-off timing corresponding to the diode conduction state of a diode connected in parallel with a switching element are detected; the values of rotor-position signals corresponding to the timings are sequentially stored; based on the stored values of rotor-position signals, a switching-element-on timing and a switching-element-off timing are calculated; and based on the timings, a gate command signal for the switching element is created.
