Description
One, technical field: the utility model relates to generator voltage stabilizing device, particularly a kind of generator voltage-stabilizing controller.
Two, background technology: the present stable-pressure device that uses, the general control circuit that adopts routine, sort circuit exists following shortcoming or deficiency: (1) transient response is bad, is difficult to accomplish all-the-way tracking during the adjustment generator voltage; What (2) Voltage Feedback adopted is mean value rather than effective value, that is to say that what generator was stable is ac output voltage mean value, rather than effective value, and therefore, stablizing effect is poor; (3) defencive function is perfect inadequately, and what have has only overcurrent protection and do not have overvoltage protection and overtemperature protection, perhaps has only wherein two kinds of protections.
Three, summary of the invention: the purpose of this utility model just provides a kind of generator voltage-stabilizing controller, shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art.
Generator voltage-stabilizing controller described in the utility model, comprise generator frame and go up overtemperature protection, overcurrent protection and the overvoltage protection of installing, also comprise the electronic circuit that is electrically connected with described overtemperature protection, overcurrent protection and overvoltage protection: comparison circuit, its effect are the width of size, adjusting and the trigger impulse of comparison output voltage and setting voltage; The adjustable voltage benchmark that is connected with comparison circuit, protection interface, transient suppress, effective value detecting circuit and level comparison circuit, its effect is respectively that the adjustable voltage benchmark carries out the manual adjustment output voltage; The protection interface uses for external circuit; Transient suppress prevents the too fast variation of output current and causes wild effects such as self-excitation; The effective value detecting circuit is converted to AC signal the voltage signal that is directly proportional with the output voltage real effective; Level comparison circuit, the dc error signal voltage with comparison circuit produces becomes pulse-width-modulating signal, keeps the suitable boring ratio that accounts for.Square wave/the triangular-wave generator that is connected with level comparison circuit, effect are that triangular wave is used for dc error signal is become pulse-width-modulating signal, and square wave is used to produce the minimum pulse width signal; Minimum conducting pulsewidth circuit, its effect are to prevent to account for boring ratio to reach 100% or reduce to zero; Output driving circuit, its effect provides the silicon controlled power signal, adjusts its angle of flow; Continuous in turn voltage sample circuit, output voltage circuit and exciting controllable silicon circuit between effective value detecting circuit and the output driving circuit, its effect is respectively: feed back to voltage signal that is directly proportional with output voltage of system, be exactly the size of output voltage, adjustment exciter current of generator and the output voltage of generator.
Wherein, described transient suppress also is connected with level comparison circuit.Described square wave/triangular-wave generator also is connected with minimum conducting pulsewidth circuit.Described minimum conducting pulsewidth circuit also is connected with output driving circuit.
The utility model has following advantage compared with prior art:
1. employing electronic circuit, system stability be the real effective of output voltage, rather than mean value;
2. has the function that output voltage can arbitrarily be adjusted;
3. has perfect defencive function;
4. have good load tracking performance, when the load current wide variation, output voltage is still very stable.
