摘要： A battery isolator for an electrical system that includes at least a first battery and a second battery, wherein a negative terminal of each of the first and second batteries are connected together at a ground point and a charge source is connected in parallel with one of the first and second batteries. The battery isolator comprises an inductor having a first terminal and a second terminal, a first switch connected between a positive terminal of the first battery and the first terminal of the inductor, and a second switch connected between a second terminal of the inductor and a positive terminal of the second battery. The first and second switches are selectively actuated in a predetermined manner, such that the battery isolator can be used to charge one of the first battery and the second battery. At least one of the first and second switches may be selectively actuated to prevent one of the first and second batteries from substantially discharging the other battery when a charge source is not present.

摘要： In a magnetic bearing system, the longitudinal shaft position is shifted relative to the bearing position so that a force can be applied by the bearings away from a node at critical shaft speeds. In one embodiment, the shaft is shifted by end thrust bearings back and forth on an integral cycle basis. Alternatively, closely-spaced bearing pairs may be used and energized alternately on an integral cycle basis in order to shift back-and-forth the region at which the combined effective force of the bearing is applied.

摘要： A pulse-width-modulated inverter in which equations relating switching angles, d.c. link distortion and a.c. inverter output distortion are determined empirically or by computer modeling. The amplitude of a d.c. link harmonic is the equation variable and stored constants particularize the equation for the phase of the harmonic and each switching angle which is to be controlled in response to d.c. distortion. As the d.c. link harmonics change, switching angle modifications are calculated using the stored constants.

摘要： An inverter controller adjust a selected switching pattern to accommodate minor variations and loads in the neighborhood of that pattern. Pulse width modulated (PWM) patterns are determined for a range of loads and link ripple. For a pattern in use having A independent switching events, an A.times.B matrix is computed, where B is the number of controlled harmonics. The matrix elements represent sensitivity of controlled haromonics with respect to individual switching angles .theta..sub.i. The elements are ##EQU1## where n is the harmonic number of the controlled harmonic and .theta..sub.i is an independent switching angle. An unbalance vector comprised of the Fouier coefficient of the controlled harmonics in the inverter output is determined. This vector is a measure of the goodness of fit of a selected pattern for link ripple and load variation encountered with the selected pattern. The unbalance vector is compared to a threshold, and if the vector is less than the threshold, the switching pattern is used without modification. Otherwise, individual switching angle adjustments are calculated by dividing the unbalance vector by the sensitivity matrix.
