The big energy surge of time, can cause the damage of above-mentioned protection device first, and then cause subsequent short circuit to damage.By above-mentioned principle
In the same way, for some special electrical equipments, such as direct current servo driver, if single DC supply input is required, no
Special control power supply is provided, while the voltage of power supply is higher, such as more than 100VDC, then the control inside servo-driver is electric
Source design faces larger challenge, can then solve the problem using the circuit.The requirement to user's external power source is reduced, it is convenient
User uses, while reduces volume, reduces cost.
Utility model content
In order to solve the above problems, high current directly can be converted into the small straight of stabilization the utility model proposes a kind of
Stream, can effectively suppress direct current and surge, practical voltage is maintained at the direct current surge suppressor of low-voltage tolerance range.

A kind of direct current surge suppressor, including the inspection of direct-flow input end, DC output end, ground wire, power field effect pipe, voltage
Survey and output storage capacitor, the power field effect pipe are connected between direct-flow input end and DC output end, the output storage
One end connection DC output end of energy electric capacity, other end connection ground wire, the voltage detecting include two test sides and control terminal,
Described two test sides connect the both ends of electric capacity respectively, and the control terminal connects power field effect pipe.
Further, the voltage detecting includes resistance and triode.
Further, output the pressure-resistant of storage capacitor is 150-200V, and the capacitance of the electric capacity is 100 μ F.
Further, the resistance value of the resistance is more than or equal to 50 Ω.
Further, the power field effect pipe is on off state.
Further, the test point of two test sides of the voltage detecting is in power field effect pipe and output storage capacitor
Between.

The utility model direct current surge suppressor, its advantage are：
(1) when the voltage exported by the detection of voltage detector on storage capacitor is 28V, voltage detecting circuit makes power
FET normally, once the voltage on output storage capacitor exceedes the threshold voltage (36V) of setting, then voltage detecting is electric
Road switch-off power FET, cuts off the electricity supply and subsequent conditioning circuit contacts, and is that subsequent conditioning circuit is powered by storage capacitor.Work as energy storage
Voltage on electric capacity drops to after 28V, and voltage detecting circuit opens power field effect pipe again, and it is storage capacitor to make power supply
Power supply.
(2) it is that power field effect pipe works on off state, so that the voltage on output storage capacitor is no more than setting
Value.Both subsequent conditioning circuit is protected, excessive power attenuation will not be caused again, the wide fluctuations of motor busbar voltage is prevented, carries
The high service life of motor, avoids external power supply, reduces cost, and volume reduces, and stability is good.
(3) the clamp voltage of voltage detecting is generally 36V, can mitigate the voltage stress of storage capacitor, prevent various
Voltage fluctuation within a narrow range caused by factor and false triggering power field effect pipe frequent operation improve power field effect on off state
Should pipe life-span, reduce switching loss.
