摘要： A power converter for an electric rotating machine is provided which is designed to ensure a desired length of a current flywheel duration in which current is permitted to freewheel from the electric rotating machine even if the power converter is in a transient state or subjected to an unexpected change. The power converter is equipped with a controller and a switching circuit which is disposed between a power supply and windings of the electric rotating machine. The switching circuit has switches grouped into an upper and a lower arm. The controller works to control an off-operation of one of the switches of one of the upper and lower arm so as to produce a desired length of the current flywheel duration following turning off of the one of the switches, thereby minimizing a loss of rectification and avoiding the backflow of current from the power supply to the windings.

摘要： A generator has a field coil of a rotor, an armature coil of a stator, a control device supplying an exciting current to the field coil when detecting rotation of the rotor, and a control circuit alternately setting an upper arm transistor and a lower arm transistor in on state in a rectifier module to generate a phase voltage. The control device detects the rotation from a periodic change in a sign of the difference between the phase voltage and a reference voltage. When the rectifier module is overheated, the control circuit sets the upper arm transistor in the off state and sets the lower arm transistor in the on state to almost fix the phase voltage, the control device detects no rotation and stops supplying the exciting current, and the rectifier module generates no phase voltage to decrease temperature of the rectifier module.

摘要： In a rotary electric machine, a load-dump protector turns on a switching element as a low-side rectifying element for at least one of plural-phase stator windings when the output voltage exceeds a first threshold voltage due to load dump. The load dump protector determines a turnoff timing of the switching element as the low-side rectifying element for the at least one of the plural-phase stator windings after the output voltage, which exceeded the first threshold voltage once, falls below a second threshold voltage. The second threshold voltage is set to be lower than the first threshold voltage. The load dump protector turns off, at the determined turnoff timing, the switching element as the low-side rectifying element for the at least one of the at least two-phase stator windings.

A diode is connected in parallel to each switching element. One end of the switching element of each of the upper arms is connected to a positive terminal of a battery and one end of the switching element of each of the lower arms is connected to a negative terminal of the battery via a vehicle body. The switching section rectifies induced phase voltage of an armature winding. A section sets ON-timing of the switching elements. A section sets OFF-timing of the switching elements. When the switching element of each lower arm is OFF, a detector detects an energization period in which current flows to the diode. A calculator calculates a rotation frequency based on the detected energization period.

摘要： A vehicle generator includes armature windings, rectifier module groups, an upper MOS on-timing determining section, a lower MOS on-timing determining section, a rotational speed calculating section, a target electrical angle setting section for setting a value of a target electrical angle, an upper MOS off-timing determining section, a lower MOS off-timing determining section, and drivers for driving high-side and low-side MOS transistors constituting upper and lower arms. The target electrical angle represents a margin period between when the low-side MOS transistor was turned off a half cycle ago and the moment when the lower arm on-period has ended. The upper MOS off-timing determining section and the lower MOS off-timing determining section set off timings of the MOS transistors such that the margin period is equivalent to the set value of the target electrical angle.
