Accompanying drawing explanation
Fig. 1 is the principle schematic of a preferred embodiment of the utility model solid state distribution device working power circuit.
Fig. 2 is solid state distribution device working power circuit principle schematic of the prior art.
Embodiment
In order to understand the utility model solid state distribution device working power circuit better, below in conjunction with accompanying drawing, explanation is further elaborated to the utility model one preferred embodiment.
The present embodiment as shown in Figure 1, in solid state distribution device working power circuit, arranges three power modules.Power module A is input as working power busbar A, and power module B is input as working power busbar B, and power module C is input as power flow concentration bar.Three antireflux diodes are all set at CPU module, Signal-regulated kinase, each solid-state power controller passage, respectively the output current from three power modules are processed.
Use power input busbar to power as power module C powers, the problem that the power down of working power busbar causes whole equipment working power to lose efficacy can be solved.
Cancel the antireflux diode before power module, input circuit single point failure before solution power module, causes the problem that whole equipment working power lost efficacy.
By the output of working power circuit three power modules, be connected to each module (CPU module, Signal-regulated kinase or any one solid-state power controller passage), improve module work power supply reliability.
Antireflux diode is separately positioned in each module (CPU module, Signal-regulated kinase or any one solid-state power controller passage), individual module working power single point failure can be prevented, cause whole equipment working power circuit to lose efficacy.
More than be described in detail in conjunction with specific embodiment of the utility model, but be not to restriction of the present utility model, everyly according to technical spirit of the present utility model, technical scope of the present utility model is all belonged to any simple modification made for any of the above embodiments, also it should be noted that, comprise the combination in any between each part mentioned above according to the category of solid state distribution device working power circuit technical scheme of the present utility model.
