Abstract:
A strapping machine having a movable working assembly includes comprises a machine body, a chute, and a movable working assembly. This machine body contains a storing space. The chute has an upper chute portion and a lower chute portion. The movable working assembly which is in the storing space includes a horizontal movable portion, a vertical movable portion, a working device, and an operation linkage mechanism. When the vertical movable portion moves to the move-down position, the lower chute portion is separated from the upper chute portion. Then, the movable working assembly can be moved out for easy maintenance. So, it is quick and easy to repair any internal device or part inside the strapping machine. The repairer does not need to stoop or squat down for repairing it. In addition, it saves strength and time to move out the working device or related part.

Abstract:
A bi-directional DC to DC power converter includes two DC sources, two inductors respectively connected to the two DC sources, a first switch and a second switch respectively connected to the two inductors, two capacitors respectively connected to the two switches, and a third switch connected between the two inductors. The first, second and third switches are respectively connected reversely with a diode in parallel. When the third switch is alternately turned on and off and the first and second switches are always turned off, the power converter operates as a boost power converter and electric energy flows from the two DC sources to the two capacitors. When the third switch is always turned off and the first and second switches are synchronously turned on or off, the power converter operates as a buck power converter and electric energy flows from the two capacitors to the two DC sources.

Abstract:
A DC to AC inverter has a DC power input port, a buck converter, a buck/boost converter, an output filter and an AC output port. The DC power input port has a positive input terminal and a negative input terminal, both connected to a DC source. The AC output port is connected to a single-phase utility system. When the single-phase utility system is in positive half cycle, the buck converter generates a positive half-cycle signal of sinusoidal current. When the single-phase utility system is in negative half cycle, the buck/boost converter generates a negative half-cycle signal of sinusoidal current. In either the positive or negative half cycles, only one power electronic switch is switched in high frequency to reduce switching loss. Further, the negative input terminal of the DC power input port of the invention can be connected to a neutral line of the single-phase utility system.
