摘要： A method for controlling a multi-phase rotary electric machine is disclosed. The stator of the machine is controlled by a control bridge having a plurality of parallel mounted switching arms, with each arm comprising a high-side switch and a low-side switch connected at a center tap connected to a phase of said rotary electric machine. The machine operates as a generator and is connected to an electrical network on board a motor vehicle. The method involves short-circuiting a phase winding of the stator when a measurement of the voltage of said network exceeds a first predetermined value, and after this, activating a switching arm, the center tap of which is connected to said at least one short-circuited phase winding, during which the intensity in the short-circuited winding is measured, if the measured intensity is positive, the high-side switch of said activated switching arm is moved to the closed position, otherwise, it is moved to the open position.

摘要： A control device stores a plurality of operation patterns associated with each of synchronous numbers and modulation factors, and the synchronous numbers each define the upper limit of the number of switching operations for each switch constituting an inverter. The control device selects an appropriate operation pattern from among the stored operation patterns, and operates each switch on the basis of the selected operation pattern. The control device stores a plurality of operation patterns associated with the same modulation factor for the same synchronous number. In a case where there is a plurality of next patterns as operation patterns corresponding to a next modulation factor, the control device selects, from among the next patterns, an operation pattern with a small change from a currently set operation pattern.

摘要： In a power converting device, a controller determines a combination pattern of a first energization pattern for the first set of the at least one-phase winding and a second energization pattern for the second set of the at least one-phase winding. The first and second energization patterns respectively include at least a first energization duration for the first set of the at least one-phase winding and a second energization duration for the second set of the at least one-phase winding. The controller supplies a drive pulse signal, whose on duration is based on the determined combination pattern, to the switch to thereby control on-off operations of the switch.
