Patent GB-2589296-A (GB)
Title: Feedback controlled gate driver
Inventor: FELLIPE SALDANHA GARCIA
IPC: H03K17/16
Filed: 2019-09-24
Abstract: A gate drive circuit 100 for providing a controlled gate signal to an electronic switching module 110 comprises an amplifier 105, current derivative (di/dt) and voltage derivative (dv/dt) sensing means 102,104, and on-current derivative, off-current derivative, on-voltage derivative and off-voltage derivative feedback gain control means 120, 115, 125, 130. The current derivative sensing means measures di/dt between a kelvin terminal and a power terminal of the switching module and feeds back a current derivative feedback signal corresponding to di/dt. The voltage derivative sensing means measures dv/dt across a first switch terminal and the power terminal of the switching module and feeds back a voltage derivative feedback signal corresponding to dv/dt. The on-current, off-current, on-voltage and off-voltage derivative feedback gain control means are configured to adjust a gain of their associated derivative feedback signal (first to fourth gain adjustment respectively) during the relevant turn-on or turn-off period of the switching module. The amplifier controls the gate signal to adapt a switching speed of the switching module during a switching transient based on the adjusted derivative feedback signals, where the first to fourth gains are adjusted independently during at least a turn-off period of the switching module. The gate drive circuit may be used in applications requiring fast response time and low losses.

Title: Method and apparatus for expanding wellbore casing
Inventor: CHEE KONG YEE
IPC: E21B43/10
Filed: 2018-11-15
Abstract: A tool for expanding a liner in a wellbore includes a cone assembly that is moveable between a retracted position and an extended position. The tool also includes a jack assembly that is operable by fluid pressure to move the cone assembly from the retracted position to the extended position. The fluid pressure is also applied to expansion cup seals to generate axial load that urges the cone assembly to move through the expandable liner and radially expand of the expandable liner. A latch assembly axially fixes the liner while the cone assembly moves to the extended position. Once the cone assembly is fully moved to the extended position, the latch assembly releases the liner, allowing the cone assembly to move through the liner and radially expand the liner.

Title: An apparatus and methods for use in a power delivery system
Inventor: KAMALARAJ KANNAN
IPC: H01H31/10
Filed: 2020-11-26
Abstract: An apparatus for use in a power delivery system comprises a DC circuit breaker 20 with two terminals 22 that opens automatically in the event of an overcurrent. A disconnector switch 10 is connected in series with the circuit breaker. The connection to the circuit breaker acts as a common terminal that the switch can couple to one of two terminals, each connected to a different one of the polarities of a DC power supply (11, 12 fig.2a). An interlock mechanism 9 is coupled between the circuit breaker and disconnector switch to disable the circuit breaker from opening, even in an overcurrent event, while the disconnector switch is connected to a chosen one of the polarities of the DC power supply. The interlock may disable the circuit breaker by physically inhibiting movement of a contact arm of the breaker (9, fig. 4b), or by diverting magnetic flux of an electromagnetic actuator. The disconnector switch may include shutters (60, fig.9) that at least partially occlude the gap between one or more moveable contact arms and their respective contacts when they are not coupled. A changeover switch with first, second, and common terminals, and a shutter mechanism as above is also claimed. The apparatus can be used to disconnect the live cable or third rail of a DC rail network supply for maintenance.
