Abstract: A buck-boost power conversion system for converting between direct current (“DC”) voltages and alternating current (“AC”) voltages of different magnitudes can include a DC/AC switched network and an AC/AC switched network for converting a DC voltage to an AC voltage of a different magnitude with a minimized number of inductors and without using a transformer. The buck-boost power conversion system can be bidirectional such that a DC voltage can be converted to an AC voltage and an AC voltage can be converted to a DC voltage. A DC voltage can be input to the buck-boost power conversion system and an AC voltage can be output with a greater or lesser magnitude than the DC voltage. In additional or alternative examples, an AC voltage can be input to the buck-boost power conversion system and a DC voltage can be output with a lesser or greater magnitude than the AC voltage.

Abstract: A light steel connecting structure for a housing includes a supporting plate fixed to a cross beam and integrally connected to one end of a supporting block and a fixed plate. The other end of the supporting block extends in a direction distant from the supporting plate and is inclined in a vertical direction. A fixed hole is formed in the fixed plate and includes two opposite inclined surfaces forming an accommodating groove abutting against the supporting plate and receiving the supporting block. When the connecting structure is mounted, the supporting block passes the fixed hole, and presses the supporting plate, so that a friction force is generated between the supporting plate and the fixed plate to prevent them from loosing, and hence the stand column and the cross beam.
