摘要： A method for obtaining a power system phasor includes sampling a power system signal at instants determined by a nominal power system frequency to provide a plurality of data samples; using the data samples to estimate a phasor having an elliptical trajectory; generating a deviation formula representing a frequency deviation between actual and nominal power system frequencies; and using the deviation formula to perform a coordinate transform of the estimated phasor to provide a scaled phasor having a substantially circular trajectory. If the data samples are unevenly spaced, a method in another embodiment includes minimizing squares of errors between the unevenly spaced data samples and an approximating sinusoidal function of the data samples. Power system phasors can be used to detect turn faults by providing scaled current and voltage phasors; extracting fundamental voltage and current phasors; and applying a symmetrical component transform to the fundamental voltage and current phasors to obtain symmetrical component voltage and current phasors for use in determining the existence of a turn fault. Variance calculations and/or trigonometric function fits can be used to increase sensitivity of fault detection.

摘要： A power device control system includes a power device having an input gate and first and second output terminals, a controller, and a gate driver for supplying current to the input gate of the power device, comparing a voltage difference between the first and second output terminals, and providing a comparator signal to the controller if the voltage difference is greater than or equal to a predetermined maximum voltage difference. The controller is capable of providing a command signal to the gate driver and pulse width modulating the command signal upon receiving a comparator signal from the gate driver to gradually switch off the power device. The control system can further include a current sensor coupled between one of the first and second output terminals and the controller for supplying a current signal and an integrated current signal to the controller. The control system can be capable of variably pulse width modulating the command signal, and, in one embodiment, the modulation process includes varying on/off switching of the command signal to increase a percentage of off time during subsequent periods of modulation.

摘要： A bidirectional buck boost converter and method of operating the same allows regulation of power flow between first and second voltage sources in which the voltage level at each source is subject to change and power flow is independent of relative voltage levels. In one embodiment, the converter is designed for hard switching while another embodiment implements soft switching of the switching devices. In both embodiments, first and second switching devices are serially coupled between a relatively positive terminal and a relatively negative terminal of a first voltage source with third and fourth switching devices serially coupled between a relatively positive terminal and a relatively negative terminal of a second voltage source. A free-wheeling diode is coupled, respectively, in parallel opposition with respective ones of the switching devices. An inductor is coupled between a junction of the first and second switching devices and a junction of the third and fourth switching devices. Gating pulses supplied by a gating circuit selectively enable operation of the switching devices for transferring power between the voltage sources. In the second embodiment, each switching device is shunted by a capacitor and the switching devices are operated when voltage across the device is substantially zero.
