The power conversion apparatus (100) has: a charging device (14) for charging from an external power source (20) to a cell (30); an inverter (13) for converting the current of the cell (30) from direct current to alternating current and supplying the current to a motor (40); and a junction box (15) for relaying an electrical connection. The inverter (13), the charging device (14), and the junction box (15) are contained in a single housing. Also, the charging device (14) and the junction box (15) are electrically connected, and the junction box (15) and the inverter (13) are electrically connected. Also, the junction box (15) and the inverter (13) are connected by a bus bar (16).

An electronic apparatus includes a housing, a first substrate, and at least one substrate module. The housing includes side plates and a bottom plate. The side plates define the inside space having a bottom opening. The side plates include a first side plate and a second side plate connected to the first side plate. The first side plate has a protrusion protruding toward the inside space of the housing. The bottom plate is connected to the side plates to close the bottom opening. The first substrate is provided in the inside space to face the bottom plate. The at least one substrate module is provided on the first substrate in the inside space. The substrate connecting member is provided on the first substrate to face the second side plate and has a hole into which the protrusion of the first side plate is inserted.

Systems, apparatuses, and methods for a module door having a biased latching mechanism providing safety measures to prevent accidental shock or short circuit. In an embodiment, a modular inverter system may include an empty module receptacle that includes a cavity configured to receive any modular power device. The cavity may be covered by a module door that features a rigid door member. The rigid door member may have a hinge set on one edge that is further attached to the enclosure for the module. The hinge allows for the module door to rotate open and closed. The module door further includes a latching mechanism that holds the module door in a closed position when latched. The module door also includes a disengagement orifice that is configured to receive a disengagement protrusion positioned in the back side of a power module about to inserted into the empty module receptacle. The disengagement protrusion may penetrate the disengagement orifice thereby unlatching the module door and allowing the module door to swing open.

Electrical device including a printed circuit board, a sensor mounted on the printed circuit board and projecting from the PCB, and a sensor protection component including a housing in which is housed the sensor.

Object: To reduce the size of a device. Solution to Problem: A switching module according to one aspect of the present disclosure is a module used in a power conversion circuit. The switching module includes a case member formed to extend in a first direction and a second direction, one or more switching elements disposed to face the case member in a stacking direction orthogonal to the first direction and the second direction, and a pressing member configured to press at least part of the one or more switching elements toward one side in the stacking direction via the case member. The one or more switching elements are disposed closer one end portion of both end portions of the case member in the second direction.

In an electrical device, a model series of electrical devices, and a production method, in particular for a converter, having a circuit board including circuit traces, the circuit board has two similar and/or identical contact area arrays, the contact area arrays in particular transitioning into each other through rotation and/or displacement. A first contact area array of the contact area arrays is fitted with a first power module, and the second contact area array is able to be fitted with a second power module, e.g., so that a respective electric motor is able to be supplied from the respective power module.

An inverter device is provided. The inverter device according to an embodiment of the present disclosure may include: a main body housing in which an optional module is detachably installed and a first circuit module is disposed inside, and the inverter device may include an optional module installation portion; an opening portion formed in the optional module installation portion; and a connection member insertion portion disposed in the opening portion.

A panel system may include a core body having opposite sides and switching devices mounted to at least one of the opposite sides of the core body, a housing in which the core body and the switching devices are disposed, gate drivers coupled to a first side of the housing and to the switching devices, and connectors coupled to one or more other sides of the housing and to the switching devices. The connectors may receive and conduct a voltage to collector terminals of the switching devices. The gate drivers may conduct a gate voltage to gate terminals of the switching devices. The switching devices may control conduction of the voltage out of the housing via the connectors as an alternating current.

A portable welding system including a main case housing a primary welding device that facilitates a welding function of the portable welding apparatus, and a modular welding component removeably attached to a bottom of the portable welding apparatus, the modular welding component comprising a component case housing a secondary welding device that supplements the primary welding device.

An electrical apparatus disclosed herein includes first/second electrical units configured to be fixed to each other. The first electrical unit has a first surface including a connector. The second electrical unit has a second surface facing the first surface of the first electrical unit. The second surface includes a socket configured to fit with the connector. One of the first and second electrical units includes a stud bolt extending toward the other of the first electrical unit and the second electrical unit, and the other of the first and second electrical units includes a bolt hole through which the stud bolt is configured to pass. When the second electrical unit is separated from the first electrical unit with the second surface facing the first surface, a bolt-hole distance from the stud bolt to the bolt hole is shorter than a connector-socket distance from the connector to the socket.
