The invention relates to a direct-current blocking circuit, and a hybrid circuit device, a transmitter, a receiver, a transmitter-receiver and a radar device that have the direct-current blocking circuit. A dielectric substrate (2) is provided with a conductor layer (3) disposed parallel with ...
A direct current blocking circuit (18) adapted for use with an electrical load (14). First (12) and second (20) blocking devices are coupled in series with each other and in series with the electrical load (14) for substantially blocking the passage of direct current through the load (14...
Multiple backup firing circuits are provided which activate the low impedance bypass path in the event of failure of the main firing circuits or of the blocking device control system. The effectiveness of the DC blocking device is continuously monitored using a DC current sensing circuit which is ...
The d.c.-coupling and a.c.-blocking circuit, for connecting across the inputs of telephone equipment, consists of a transistor (Ts1) connected by its collector to one input of the equipment (1) and by its emitter over a resistor (Re1) to the second input. The transistor's base/collec...

Analysis of Modular Multilevel Converters with Dc Short Circuit Fault Blocking Capability Bipolar HVDC Transmission Systems This project proposes a model predictive control (MPC) method for modular-multilevel-converter (MMC) high-voltage direct current (HVDC). To control the MMC-HVDC system properly,...
In order to reduce the circulating current in the primary side, a blocking capacitor is used to reset the primary winding current of the TL converter. Moreover, the rectifier stage is composed of four diodes in the center-tap rectification, forcing the circulating current at the primary side ...
The circuit reduces interfering oscillations in the active reduction circuit in telephone transmission cables. It will separate and remove the direct current component and these oscillations are either suppressed or pushed outside the working range of the amplifier. The pilot strand will also carry an...
