摘要： Provided is a loading and unloading device capable of allowing a user to easily transfer electronic devices, which are heavy and received and piled up in multi-stages, to a predetermined place although the place is narrow. The loading and unloading device of the present invention includes a cage storing the electronic device received in a housing part formed in a distributing board in a lattice form and a suspension supporting the cage storing the electronic devices to be lifted. The suspension includes a pillar vertically positioned on the ceiling surface of the distributing board and a hoisting winch attached to the pillar. The cage includes a frame body having a sheet unit where the electronic device is mounted and a connection unit connected to the hoisting winch.

摘要： PURPOSE: A serial multiple power conversion device is provided to reduce the harmonic current of a primary winding. CONSTITUTION: A serial multiple power conversion device(1) is comprised of the followings: a multiple transformer(10) which distributes the AC power which is inputted to a primary winding(11) to m×n(n and m are relative prime) number of a secondary winding(12) and a power conversion unit(20) which has m×n number of single-phase power converter(21a~21f) which are connected to the m×n number of the secondary winding, respectively, and comprises m number of output phases by connecting an output of n number of the single-phase power converter, respectively. The multiple transformer has the difference in voltage phase of 60/n of the n number of the secondary windings, which are connected to n number of single-phase power converters of the same output phase; and the difference in voltage phase of 60/m of the m number of the secondary windings, which are connected to m number of single-phase power converters corresponding to m number of output phases.
