Diagnostics and control circuit

A circuit for self-diagnosis and control comprising a plurality of processing devices each having a voltage supply, the processing devices being arranged to communicate with one another and being arranged to be electrically isolated from each processing device having a different voltage supply.. . ... Control Techniques Limited

07/30/15 / #20150212962

Servo drive device

A device is provided in which messages are received from a backplane through backplane connectors. Switching circuitry identifies which messages received from the backplane are intended for the operational circuitry of the device and interprets the input/output protocol of such messages while returning messages not intended for the operational circuitry to the backplane. ... Control Techniques Limited

07/16/15 / #20150200624

Method and system for controlling a power output of an inverter

According to a first aspect of the disclosure, there is provided a method of controlling a power output of an inverter. The method comprises measuring an output current of the inverter, determining a difference between the output current and a reference current, and controlling a reference input voltage of the inverter as a function of the determined difference. ... Control Techniques Limited

06/25/15 / #20150181745

Mounting latch

A mounting latch for mounting a device to a rail is provided. The mounting latch comprises: a moveable actuator having a profile; a latch mechanism comprising first and second opposed rail engaging members, at least one of the members having a face for causing the member to yield against a bias source when the latch mechanism is engaging with the rail; and a follower enabling the at least one member to follow a rotational movement of the actuator such that movement of the actuator in a first direction causes the at least one member to become unlatched from the rail.. ... Control Techniques Limited

06/25/15 / #20150177287

Capacitor failure

A circuit is arranged to detect a voltage imbalance indicative of component failure and, upon such detection, convey an optical signal to indicate that a component appears to have failed.. . ... Control Techniques Limited

06/04/15 / #20150155794

Short circuit protection

A method and apparatus are provided for short circuit protection in a dc current source. A rectifying circuit arranged to generate a dc output can coupled to an ac source and a capacitor filter circuit can be provided to smooth the dc output. ... Control Techniques Limited

04/30/15 / #20150115714

Method and system for powering a load

A method of controlling an electrical power supply to a load, wherein said load has an associated power threshold, is provided. The method comprises using a first electrical power source to generate a first amount of power for supply to the load, wherein said first electrical power source comprises a renewable source, and determining whether to supply a second amount of power to the load from a second, different electrical power source. ... Control Techniques Limited

03/05/15 / #20150061639

Dead-time selection in power converters

A method is provided of determining a time interval between switching events for a switching device in a power converter, the switching device being for coupling a direct current (dc) source to provide an alternating current (ac) output at a particular switching frequency. The method comprises selecting an initial length of a time interval between a first switching event and a second, subsequent switching event for the switching device and obtaining a current measurement value for the switching device when the time interval between the first switching event and the second, subsequent switching event takes said initial length. ... Control Techniques Limited

02/05/15 / #20150036400

Modulation of switching signals in power converters

There is provided a method and control system for controlling a switching device in a power converter according to a modulation scheme. The switching device couples a direct current (dc) source to provide an alternating current (ac) output at a particular switching frequency. ... Control Techniques Limited
