Description
Technical field
The use of electronic component
Background technology
Since the appearance for having semiconductor, various various electronics are made with the material of semiconductor
Element, has diode, has triode, has and do rectification, has and does amplification, has and makes voltage stabilizing.
And coming out one after another with various electronic components, electronic circuit also develops into variation.Mu balanced circuit is
Through becoming the indispensable circuit of circuit in many electrical appliances.
Mu balanced circuit needs to use voltage-stabiliser tube, and production has voltage-regulator diode and voltage stabilizing triode, voltage stabilizing to voltage-stabiliser tube at present
It is called three-terminal voltage-stabilizing pipe to triode custom, and three end underwater pipeline stabilizings are divided into adjustable three-terminal voltage-stabilizing pipe and nonadjustable fixed three-terminal voltage-stabilizing again
Pipe.
In general, with respect to than fixed three-terminal voltage-stabilizing Guan Yaogui, circuit structure in adjustable three ends underwater pipeline stabilizing price
Relative is complicated, and existing this technology provides the parameter and voltage stabilizing value that can change fixed three-terminal voltage-stabilizing pipe.
The content of the invention
1st, the adjunct circuit of fixed three-terminal voltage-stabilizing pipe parameter, its feature can be changed：Input in fixed three-terminal voltage-stabilizing pipe,
Ground terminal, output end can go here and there diode, can increase its voltage stabilizing voltage in common series diode, in output end
Series diode can reduce its voltage stabilizing voltage, and can reduce the magnitude of voltage that it is born in input series diode makes entirely
Three end pipes are unlikely to excessive heating, and the number that regulation seals in diode can just be changed accordingly, in ground terminal series connection number
More, its voltage stabilizing value voltage is bigger, just smaller in output end more its voltage stabilizing value voltages of series connection number, in input string
The more input voltages that it is born of connection number are just smaller, and the heating of homogeneous tube is fewer, and the sense of current that diode is accessed is suitable
The current direction of three-terminal voltage-stabilizing pipe.
This adjunct circuit on fixed three-terminal voltage-stabilizing pipe can make to fix the parameter change of three-terminal voltage-stabilizing pipe, particularly
Voltage stabilizing value, it can make the requirement on demand of the voltage of original nonadjustable voltage stabilizing value become to increase or decrease and become adjustable steady
Volt circuit.
The voltage stabilizing value for meeting mu balanced circuit voltage stabilizing value bigger than voltage-stabiliser tube or small can be gone with the method for this adjunct circuit,
It is exactly that the three-terminal voltage-stabilizing pipe of Na Yinding is done and is adapted to the mu balanced circuit of bigger than it or small voltage stabilizing value and uses.

Specific embodiment
It is existing certain fix voltage stabilizing value three-terminal voltage-stabilizing pipe public wiring ground terminal, no matter positive voltage output type or
To seal in one or more common diodes thirdly holding in negative voltage output type, the series connection of diode is the electric current along it
Flow direction forms drop-over, and so it can just make the voltage stabilizing value of original pipe increase or decrease and reduce heating, such as this fixes three ends
Voltage-stabiliser tube is 7805 models of positive voltage output, and its fixed output end is positive 5V voltages, if in common port i.e. ground terminal
Seal in a diode along current direction and be connected to ground wire again, then its output end voltage over the ground also reformed into 5 points it is several
The voltage of volt, if the diode of series connection is two, the forward voltage drop of diode is 0.7V, then one diode of series connection this
The output voltage of individual mu balanced circuit is just raised to 5.7V from original 5V, if the diode of series connection is two.So its voltage stabilizing
Voltage just becomes to be raised to 6.4V from 5V, analogizes with regard to this.
Fixed in the middle of voltage-stabiliser tube at the end of identical three, if not its voltage stabilizing value of increase, and need to reduce voltage stabilizing voltage,
The diode so connected is not to be connected on common, but it is concatenated into the output end of the pipe, that at this moment output end pass through
The just relative reduction of voltage after diode over the ground, that reduce to one diode of string from original 5V is 4.3V, goes here and there two two poles
Pipe is 3.6V, and it can reduce original fixed voltage stabilizing value.
When the electrical appliance power of voltage-stabilized power supply supply is quiet big or voltage of input is higher, voltage-stabiliser tube that is causing is obvious
When heating increases, the caloric value of pipe can be improved in input serial number diode, diode is also suitable both positive and negative polarity
The input current direction of voltage-stabiliser tube, such series connection accesses the voltage that can be apportioned and be applied to voltage-stabiliser tube, so as to reduce pipe
Caloric value, it is ensured that pipe energy normal work.The output current of two poles should be it is close with voltage-stabiliser tube, or quiet for more greatly,
With the diode of different forward voltage pressure drops, resulting voltage stabilizing value is different.
