Description
Technical field
The utility model is related to switch cabinet equipment field of terminal technology, and the 500W electricity of output is more particularly to overloaded based on high power
Source module.
Background technology
Switch cabinet equipment terminal is developed so far, and the stability acted to high-voltage switch gear, reliability operation is even more important.
Current tale quale is roughly divided into three kinds：
One kind is many high-voltage switch gear motors while when starting, power module can overload protection, stopping output, work(to be overloaded
After rate is eliminated, recover output, one kind is that many high-voltage switch gear motors cannot will be taken turns starting, also one kind is while start
Large-capacity battery is accessed in 500W power modules, by battery offer overload power during overload, but this mode, overload times
Number is limited.Realize that 500W power modules high power overloads power output mode, it is necessary to improve the shortcoming of conventional modules mode, with
It is almost not have overload capacity power output toward mode, overload capacity is provided by battery, work as accumulator property, the life-span declines
Afterwards, electric motor starting that may only be in single starting switch cabinet, reduces switch cubicle operating efficiency.
Utility model content
Based on the deficiencies in the prior art, the purpose of this utility model is to provide a kind of 500W electricity that output is overloaded based on high power
Source module, improves overload fan-out capability.
To achieve the above object, the technical solution of the utility model is：
A kind of 500W power modules that output is overloaded based on high power, including the EMC devices being sequentially connected（1）, AC/DC rectifications
Filtration module (2), power conversion modules (3) and power output rectification filtering module (4), the EMC devices（1）Input connect
AC220V power supplys are connect, the power output rectification filtering module (4) is connected with the battery charging and discharging management of parallel connection（5）And PWM
Modulation circuit（6）, the PWM circuit（6）The power conversion modules are connected by way of negative-feedback（3）.
The power conversion modules (3) include high frequency transformer and are connected to the high pressure of the input of high frequency transformer two
Switching tube.
The beneficial effects of the utility model are：Overload fan-out capability is improved, power outputs are overloaded up to 3 times, in addition it is short
Time is up to 4 times of overload powers；
The high frequency transformer of power conversion modules (3) and the injectron for being connected to the input of high frequency transformer two, be
The on-off mode of double tube positive exciting, output impedance is designed to smaller, and limited improves overload fan-out capability.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Embodiment
The technique effect of design of the present utility model, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belongs to the model of the utility model protection
Enclose.
It is a kind of based on high power overload output 500W power modules, including be sequentially connected EMC devices 1, AC/DC rectifications filter
Ripple module 2, power conversion modules 3 and power output rectification filtering module 4, the input connection AC220V power supplys of EMC devices 1,
Power output rectification filtering module 4 is connected with battery charging and discharging management 5 and the PWM circuit 6 of parallel connection, PWM circuit 6
The power conversion modules 3 are connected by way of negative-feedback.
Power conversion modules 3 include high frequency transformer and are connected to the high-voltage switch gear of the input of high frequency transformer two
Pipe.
After module access AC220V power supplys, the interference signal on power network can be removed in EMC devices 1, while thunder can be suppressed
Break up bad, afterwards to by high-voltage rectifier bridge, high-voltage capacitance composition AC/DC rectification filtering modules 2 become dc source, then to power
Conversion 3, mainly by injectron, high frequency transformer, using the on-off mode of double tube positive exciting, this mode can greatly increase defeated
Go out power, while being equipped with powerful high frequency transformer, high power overload power output can be achieved.The dc source of now pulse is defeated
Power output rectification filtering module 4 is sent to, by high magnetic, the inductive element of low D.C. resistance is constituted, and whole circuit is designed to
Low-down output impedance circuit, is that high power overload output ensures good path.Power output rectification filtering module 4 is parallel with
Battery charging and discharging management 5.Charge Management is provided for external battery, battery can also provide bigger power output.PWM
Modulation circuit 6 is negative-feedback PWM circuit, it is ensured that the stability of output voltage.
It should be noted that simply preferred embodiment of the present utility model described above, the utility model not office
It is limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, should all belongs to this practicality new
The protection domain of type.
