Abstract: A power supply chassis has at least one accommodating slot therein. Two side walls of the accommodating slot of the power supply chassis are provided with a first left guiding and fixing block and a first right guiding and fixing block. The guiding and fixing blocks have a first left guiding bevel and a first right guiding bevel facing a front side of the accommodating slot, a first left fixing plane and a first right fixing plane corresponding in position to the middle of the accommodating slot. When a power supply is placed into the accommodating slot, the first left guiding bevel and the first right guiding bevel guide the power supply to a middle position of the accommodating slot, and the power supply is clamped by the first left fixing plane and the first right fixing plane to enhance the stability of the power supply.

Abstract: A master/slave control system of an AC/DC power supply includes a master device. The master device is able to supply AC and DC power. The master device is connected with a plurality of slave devices through a plurality of local area network transmission interfaces. The slave devices are able to supply AC and DC power. Through the local area network transmission interfaces, a control signal can be transmitted fast for the mater device and slave devices to carry out a master/slave control. The signal transmission efficiency of the master/slave control can be enhanced greatly, so that the master/slave control is more fast and prompt. The present invention avoids the arrangement of the traditional series data communication interface and the controller area network, and simplifies the configuration and wiring of the master device and the slave devices.

Abstract: A flyback controller featuring bidirectional power control and parallelly-connected power modules is based on flyback DC-DC converters for allowing bidirectional energy flow and transformation. The flyback controller includes two bidirectional DC-DC converters that are connected in parallel. The bidirectional DC-DC converters are electrically connected with a digital-signal processor. The digital-signal processor controls the bidirectional DC-DC converters and current thereof, so that the current flows evenly across the bidirectional DC-DC converters. Thereby, the flyback controller has advantages about simplified components and increased power output, and is suitable for testing secondary batteries.

Abstract: A power circuit of an AC power supply includes a power input unit connected to a AC/DC converter. The AC/DC converter is connected to a DC/DC circuit, and the DC/DC circuit is further connected to an adjustable DC voltage regulation circuit. The adjustable DC voltage regulation circuit is connected to an amplifier to amplify and convert the DC voltages into the AC voltages, thereby outputting different AC voltages and electric currents under the condition of not switching off the output when adjusting the voltage via cross position, so that a power level is switched promptly and a very low power distortion.
