Patent DE-2857198-A1 (DE)
Inventor: LIPO THOMAS ANTHONY
IPC: H02P27/06
Filed: 1978-07-18
Abstract: A decogging feedback control for current source inverter motor drives uses a change of instantaneous torque feedback signal with no dc component that is a function of only the instantaneous pulsating component of measured torque. The change of torque signal modulates the voltage applied to the dc link and therefore the dc link current to materially reduce the detrimental cogging torque pulsations and stabilize the motor, and can be switched out at a low frequency above which it is not needed so that the motor can respond properly to rapid variations in torque.

Title: Switching matrix fault location by resistance measurement - parallels all columns with one value resistor and all rows with another
Inventor: DROTZIGER WOLFGANG ING GRAD
IPC: H04Q1/24
Filed: 1979-07-23
Abstract: A switching matrix is tested by commoning all the columns, a to h, via equal resistros, R1, and all the rows, 1 to 4, via equal resistors, R2, where R1 is different from R2. The resistance between the common points is measured by connecting them in series with a resistor, R3, across a supply (UB) and measuring the drop (UM) across R3 with a digital voltmeter (DVM). With no faults, operating any one point, e.g. a1, gives R1 + R2. If, by fault, another point operates as well, the resistance shows whether it is in the same column, same row, or different column and row. Thus and a3 gives R1 + R2/2, a1 and f1 gives R1/2, and g4 gives (R1 + R2)/2.

Title: Three=phase DC=AC converter - has steps per period increased by turning thyristors off and then some on again at given times
Inventor: FINKE REINHARD ING GRAD
IPC: H02M7/48
Filed: 1979-09-05
Abstract: The dc/ac converter consists of three series pairs of thyristors connected in parallel. Each thyristor is shunted by an antiparallel diode. The three parallel pairs are connected between the dc supply poles. The connection point between each thyristor in each pair forms one of the three phase outputs. Adjacent thyristors are controlled 120 degrees apart and the two series thyristors in each pair are controlled 180 degrees apart. The control unit (20) turns each thyristor off after 150 degrees. The control turns all thyristors off 30 degrees after the turn-on of any thyristor and then turns on again those thyristors whose turn-on time of 150 degrees has not yet elapsed.
