Description
Technical field
The utility model relates to electronic circuit technology field, is specifically related to a kind of adjustable power supply electronic load control system.
Background technology
The common direct supply electronic load in market is all have employed to dissipate by controlling electric energy conversion that power tube directly inputs with PWM mode in order to heat energy substantially in the principle of fictitious load, do like this and can produce very large drawback, first the waste casting aside electric energy is not said, concentrate the talk of the heat power consumption that will dissipate hundreds of watts and just need quite huge heating radiator, this proposes a structural difficult problem to the design of large power supply electronic load undoubtedly, add design cost, limit the Development Feasibility of large power supply electronic load.Certainly the product of minority famous brand is also had to add Feedback current, so-called Feedback current is exactly be not all transform the electric energy of input in order to heat power consumption, but a part has fed back to electrical network, this is extraordinary mentality of designing, namely the loss that cost again saves electric energy is decreased, but process feed like this and can there is certain problem, first at present the most electrical network of China is still in unidirectional mode, namely user is merely able to make electricity consumption, and user's electricity enough can flow to electrical network, although distributed power generation and this electrical network of microgrid form allow the two-way use electric energy of user, also be the development trend of following intelligent grid, but just following development trend in recent years still can not large-arealy be popularized, so the feed of above form just can not be real feed back to electrical network, can only be that the consumer used with power supply electronic load parallel connection may use this part of feed.Secondly, the consumer that feed due to power supply electronic load may be connected in parallel on it utilizes, so once power supply electronic load is broken down, may produce harm to these consumers, the alternating current gone out by copped wave inversion after all civil power reliability of comparing is not high.
Utility model content
Solve the problem for this reason, we have proposed a kind of adjustable power supply electronic load control system.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of adjustable power supply electronic load control system, comprise the EEROM for the protection of power work parameter and controling parameters power down protection be connected with digital signal processing module, the module one of power amplifier board and the protection of secondary temperature detection, for completing the communication port of communication, for the module two of tested power output end electric current and voltage sampled signal input, for the module three of control load property adjuster and load adjuster, for the module four that tested power input electric current and voltage isolation adopts, for the module five of feed inverter, for the human-computer interaction module of indicator of the power supply status, analyze the electricity consumption personality modnies of tested power source loads personality modnies and the tested power supply of analysis.
Further: described communication port is RS485 port.
By technique scheme, the utility model feed part is directly that tested power supply is used, has saved valuable electric energy, and adopts all-digitized demodulator scheme, decreases the complexity of equipment, adds reliability.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and embodiment, the utility model is described in further detail.
Embodiment.
Shown in composition graphs 1:
A kind of adjustable power supply electronic load control system, comprise the EEROM102 for the protection of power work parameter and controling parameters power down protection be connected with digital signal processing module 101, the module 1 of power amplifier board and the protection of secondary temperature detection, for completing communication and the communication port 104 of employing RS485 port, for the module 2 105 of tested power output end electric current and voltage sampled signal input, for the module 3 106 of control load property adjuster and load adjuster, for the module 4 107 that tested power input electric current and voltage isolation adopts, for the module 5 108 of feed inverter, for the human-computer interaction modules such as indicator of the power supply status 109, for the human-computer interaction module 110 of indicator of the power supply status and the electricity consumption personality modnies 111 of the tested power supply of analysis.
The utility model feed part is directly that tested power supply is used, based on the PID control principle of classics, adopting tables look-up determines the way of controling parameters, solve different control response speed on different frequency range and save valuable electric energy with the control optimization reaching full frequency band, and adopt all-digitized demodulator scheme, decrease the complexity of equipment, add reliability.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
