Abstract: [Problem] In a pseudo-current source inverter which drives a motor at a high speed, a current phase adjustment is assured and facilitated to perform a field-weakening control or suppress a terminal voltage saturation at a time of the high-speed motor drive.[Means For Solving Problem]A phase advance correction is carried out for a magnetic flux phase information from which a 120 degree conduction pattern is obtained with a motor terminal voltage as a reference phase. The phase advance correction includes the correction of differentiating the terminal voltage detection signals of the motor, the adjustment of enlarging the phase advance correction quantity in a case where the motor load current is large, and delays the gate signals of the 120 degree conduction pattern in accordance with the speed estimation value through a delay counter and carries out the phase advance correction as the rising edge timing of the subsequent gate signal at the subsequent step phase. Furthermore, the error correction is carried out for the phase advance correction quantity in accordance with a variation tendency of the speed estimation value and a detection value of a direct current of the inverter.

Abstract: A generator control unit for fast field discharge of a field coil is disclosed. The generator control unit comprises a control domain for detecting an excessive generator output voltage, a buck regulator with a feedback pin fed from the control domain, and an over-voltage protection switch connected in a field coil return path which is bypassed by a voltage limiting device. The control domain receives a point of regulation voltage feedback and upon detection of an over-voltage, emits a disable signal to cause the buck switch shut off along with the over-voltage protection switch. Thus dual breaking points are created at two ends of the field coil to dissipate the field charge quickly through the voltage limiting device. When the buck switch experiences a shorting failure, the over-voltage protection switch provides a second breaking point to allow the field discharge through the voltage limiting device, thereby controlling the field discharge with directly controlled over-voltage protection switch.

Abstract: The output voltage generated by permanent magnet generator (PMG) is regulated by controlling a buck/boost voltage applied to selected sub-coils within the PMG. The PMG includes a number of stator coils that are each divided into a number of sub-coils. A buck/boost voltage source generates a buck/boost voltage, and a controller connected to monitor the output voltage generated by the PMG selectively applies the buck/boost voltage to selected sub-coils based on the monitored output voltage. In this way, the controller is able to regulate the output voltage by selectively controlling the buck/boost voltage applied to the selected sub-coils.
