Feature.
Accompanying drawing explanation
Fig. 1 is the circuit theory schematic diagram of the one-way conduction circuit of the present invention.
Detailed description of the invention
It is illustrated in figure 1 the circuit theory schematic diagram of the one-way conduction circuit of the present invention: it is this unidirectional that the present invention provides
Turning circuit, including P-channel metal-oxide-semiconductor (V1), voltage comparator (U1) and biasing resistor (R1);The drain electrode of metal-oxide-semiconductor is unidirectional
The input (IN) of circuit passband, the source electrode of metal-oxide-semiconductor is the outfan (OUT) of one-way conduction circuit, the control end of metal-oxide-semiconductor and voltage
The outfan of comparator connects;The inverting input of voltage comparator is connected with the input of one-way conduction circuit, and voltage ratio is relatively
The in-phase input end of device is connected with the outfan of one-way conduction circuit, the positive source of voltage comparator and one-way conduction circuit
Outfan, power supply (VCC) are all directly connected to, the power cathode ground connection (GND) of voltage comparator;Biasing resistor is connected to electricity
Between outfan and the positive source of pressure comparator.
P-channel metal-oxide-semiconductor can also use field effect transistor to be replaced.
The work process of the one-way conduction circuit of the present invention is: when input terminal voltage is higher than output end voltage, voltage ratio
Relatively device U1 is output as low, now P-channel metal-oxide-semiconductor V1 conducting.Because there is conducting resistance between metal-oxide-semiconductor drain electrode and source electrode, metal-oxide-semiconductor is deposited
In electric conduction pressure drop, therefore input terminal voltage is higher than output end power, and voltage comparator U1 outfan persistently exports low, metal-oxide-semiconductor
V1 is by constant conduction, and circuit presents normally state.
When input terminal voltage is less than output end voltage, voltage comparator U1 is output as height, because voltage comparator is output as
Open-drain output, the output clamper of voltage comparator U1 is high level by pull-up resistor R1.Now P-channel metal-oxide-semiconductor V1 turns off.Input
End disconnects with outfan, and circuit presents reverse blocking state.
Because P-channel metal-oxide-semiconductor V1 there are body diode, therefore, when input terminal voltage is relatively low, it is impossible to make voltage comparator just
When often working, due to the unilateral conduction of body diode, this circuit also has one-way conduction characteristic, and its voltage is reduced in metal-oxide-semiconductor
The forward conduction voltage drop of body diode.Along with the rising of input terminal voltage, when voltage rises to make voltage comparator normal
After work, its one-way conduction characteristic is realized by metal-oxide-semiconductor turn-on and turn-off.Its voltage drop is the least, thus realizes low power consumption characteristic.
The distribution line failure positioner that this one-way conduction circuit that the application present invention provides is made, has the most equally
Feature low in energy consumption.
