Biamonte Robert Anthony, Bogdanski Joseph William, Covi Kevin Robert, Meyer Herman Paul, Rafkind Daniel Ira: A regulated DC power supply having master and slave regulators.. Ibm, May 10, 1989: EP0315366-A2 (32 worldwide citation)

A d.c. power supply system comprises a plurality of voltage regulator power supplies (21, 23, 25) connected in a master slave configuration, the number of regulators being one greater than required to provide load current requirements. The master regulator (21) generates a control signal to control ...

The invention relates to a switched-mode controller for direct-voltage conversion. The storage element used is not, as hitherto customary, a storage reactor but a series resonant circuit. From the current in the series resonant circuit, a control signal is derived, in the form of feedback, via a cur ...

Reineke Joerg, Hock Alexander: A drift-compensated piezoelectric fuel injector actuator. Bosch Robert, August 11, 1999: GB2334164-A (11 worldwide citation)

Because the capacitance of a piezoelectric actuator 1 changes with temperature and age, the charge delivered to it must be adjusted to achieve a consistent driving voltage and hence a consistent extension. The potential Up across the actuator after charging is measured and the operation of the half- ...

Franks Patrick Daniel: A switching circuit. Plessey, March 30, 1983: GB2105927-A (10 worldwide citation)

A switching circuit has a load current path which comprises a series arrangement of a Thyristor (THY1) and a transistor (TR1). The gate electrode of the Thyristor (THY1) and the gate or base electrode of the transistor (TR1) are coupled with a common switching signal input. This arrangement enables ...
