  • Publication number: 20240079947
    Abstract: This document describes systems and techniques for a current-limiting control strategy for single-loop droop-controlled grid-forming inverters. In aspects, a hysteresis module is configured to compare an output current detected across one or more transistors in an inverter controlled by the single-loop droop converter with a specified maximum current and to generate an overcurrent signal. The overcurrent signal presents a fault signal responsive to the output current exceeding the specified maximum current. A logic array is configured to logically combine gate control signals generated by the single-loop droop controller to selectively direct the one or more transistors to allow the output current to flow therethrough with the overcurrent signal to present modified gate control signals to the one or more transistors.

  • Publication number: 20050040744
    Abstract: A bezel mounting assembly includes a bezel (10), a front panel (30) defining a pair of apertures (31), and a locking device (20) attached to the bezel for securing the bezel to the front panel. The bezel includes a pair of pillars (121) and a pair of blocks (11) having a pair of posts (14). The locking device includes a pair of symmetric side plates (22) defining through slots (25) for slidably receiving the posts, a pair of resilient arms (27) extending from the side plates, an operating member (23), and a pair of catches (26). The locking device is slidably attached on the blocks, with the posts engagingly received in the through slots. The resilient arms are secured to the pillars at free ends thereof. The operating member is moved vertically so as to drive the catches to engage in and disengage from the apertures of the front panel.
