Abstract: A motor box is used to rack withdrawable devices into or out of the associated cell in a switchgear cabinet. A hand held control is used to operate the motor box from a remote location. The motor box is attached to a mounting assembly on the switchgear cabinet door. The assembly can be part of the door or separately attached to the door. The mounting assembly allows for easy alignment of the motor box to the door and prevents rotation of the motor box when the box is latched to the mounting assembly. A cart is used to transport the motor box, remote control and associated peripherals to and from the switchgear cabinet.

Abstract: A method and system for applying a liner material to a contoured surface, such as an exposed rock face in an underground hard rock mine, is disclosed. Locations of a plurality of spatially distributed surface grid points on the contoured surface may be detected so as to generate a representative topographical profile of the contoured surface. Based on the plurality of surface grid points, a spray path for a liner application device configured to emit a spray of the liner material may be determined. In some cases, the spray path may have a trajectory that follows the topographical profile of the contoured surface offset therefrom within a spray range of the liner application device. Liner material may then be sprayed onto the contoured surface while controlling the liner application device to undertake at least one pass of the spray path.

Abstract: In a neutral-point-clamped power inverter, gate drive circuit comprises four drive blocks providing bipolar DC signals to control switch gates. The first and third drive blocks are bootstrapped to the second and fourth. Inverter's neutral bus is commonly connected to the positive and negative DC buses through clamping capacitors. An arm of four serially-stacked-switches bridges DC buses. The switch arm midpoint is an output of the inverter. A first clamping diode connects the neutral bus to the first switch emitter; a second clamping diode connects the neutral bus to the third switch emitter. In one embodiment, a second switch arm mirrors the first, providing a second output; a second gate drive circuit mirrors the first. A bias circuit provides two reference voltages for the gate drive circuits. Three isolated DC sources provide signals that, when used by the gate drive circuit, result in seven isolated bipolar DC signals.

Abstract: A full-bridge, NPC inverter uses pulse width modulation (PWM) to convert the DC voltage from a solar panel array to an AC voltage at the output of the inverter that is acceptable for connection to a utility. The PWM control unit has a predetermined carrier frequency. The carrier unit uses for each carrier period either positive or negative values of a reference voltage to generate a predetermined number of signals to control the switching on and off of each of the eight inverter switching elements in a predetermined pattern for a predetermined period of the carrier frequency period to thereby produce the acceptable alternating current voltage at the inverter output and not produce between the inverter input and earth ground a carrier frequency component.
