Description

Technical Field:

[0001] The present invention relates to the field of isolated bidirectional power supplies, and specifically to an isolated bidirectional power supply that is convenient for disassembly and assembly. Background Art:

[0002] A dual-power automatic transfer switch is a device controlled by a microprocessor and used for starting the switching between grid power and grid power or grid power and generator power in a power grid system, which can continuously supply power. For a series of dual-power supplies, when the normal power supply suddenly fails or power outage occurs, through the dual-power transfer switch, it automatically switches to the standby power supply. Under small loads, the standby power supply can also be supplied by a generator, enabling the equipment to still operate normally. The most common applications are in elevators, fire protection, monitoring, lighting, etc.

[0003] Isolated bidirectional power supplies are widely used, but the existing isolated bidirectional power supplies have relatively single functions. They can only be controlled to connect or disconnect the power supply through the main switch, which is not convenient for single-sided wiring. Moreover, most of the existing wiring boards are made of copper sheets, and the distance between the copper sheets is relatively close, making the wiring inconvenient, with low efficiency and slow speed.
