Abstract: An inverter assembly including a phase-control chamber and a direct current (DC) chamber. The phase-control chamber includes a direct current (DC) link capacitor electrically connected a control circuit board via multiple connectors. The DC chamber includes a ferrite filter fixed to a DC bus bar via a support component.

Abstract: An inverter is provided that includes a direct current (DC) bus bar assembly positioned within a DC chamber in the housing is provided herein. The inverter further includes a gate-driver circuit board included in a phase-control chamber in the housing, and an external communication interface in electronic communication with a power control circuit board and positioned in an external communication chamber in the housing. The DC chamber, the phase-control chamber, and the external communication chamber have varying levels of electromagnetic interference (EMI).

Abstract: Disclosed herein is a lightweight, self-propelled, hand-guided sweeping apparatus for removing debris lying on the ground, the apparatus comprising: a chassis having wheels with ground engaging flotation tires; a hopper compartment mounted pivotally on the chassis to tilt upwardly and rearwardly about the pivotal connection to dump, by gravity, its debris content; tilting structure for tilting the hopper compartment about the pivotal connection; rotary brush structure for engaging and sweeping the ground surface, the brush structure being mounted integrally, horizontally and rotatively on the hopper compartment and being open to the hopper compartment to propel the debris inside the hopper compartment as the brush structure rotates; drive structure, fixedly mounted to the chassis, for selectively driving: at least one of the wheels, the tilting structure, the rotary brush structure; control structure, mounted to the chassis, for hand-guiding sweeping apparatus and selectively operating the drive structure; wh
