Utility model content
In order to overcome the defect of prior art, it is provided that the standby power supply apparatus that a kind of simple in construction, easy to use, strong adaptability, switching are rapid, safe and reliable, the utility model discloses a kind of wind-powered electricity generation controller with internal accumulation of energy stand-by power supply.
This utility model reaches goal of the invention by following technical solution:
A kind of wind-powered electricity generation controller with internal accumulation of energy stand-by power supply, including controller, central processing unit it is provided with in controller, it is characterized in that: also include DC UPS, accumulation of energy stand-by power supply and current converter, being commonly connected to the central processing unit in controller after the parallel connection of both DC UPS and accumulation of energy stand-by power supply, the two ends of current converter connect DC UPS and central processing unit respectively.
The described wind-powered electricity generation controller with internal accumulation of energy stand-by power supply, is characterized in that: the electromotive force of DC UPS is 24V, accumulation of energy stand-by power supply selects rated operational voltage to be not less than the super capacitor of 24V, and the output electric current of current converter is 20mA.
The capacitance of super capacitor selected according to power and the predetermined discharge persistent period of central processing unit, and selection method is as follows:
C super capacitor nominal capacity, unit: farad (F)；
UratedSuper capacitor rated operational voltage, unit: volt (V)；
UminSuper capacitor terminates running voltage, unit: volt (V)；
The t super capacitor discharge period, unit: second (s)；
