In addition, described EMI filter circuit 1 is two-stage compound EMI filter circuit, for improving the EMI characteristic of circuit better; Rectifying circuit 2, for when power supply is for exchanging, the alternating-current voltage/AC voltage of input is transformed into vdc, and when power supply is direct current, rectifying circuit 2 is inoperative; DC filtering circuit 3, for carrying out filtering to the DC pulse moving voltage after rectification, provides the operating voltage of drg, also for Switching Power Supply 6 provides high direct voltage; Sampling circuit 4 uses voltage to be 110V or 220V for judging; Brake application time control circuit 5 controls the brake application time automatically according to the size of sampling voltage, ensures that, under different use voltage, the brake application time of drg is constant; Switching Power Supply 6 is 15V Switching Power Supply, for providing inner 15V direct supply; Frequency jitter pulse-width modulation circuit 7 is for receiver voltage reactive circuit 9 the drg trigger voltage sent and the sampled signal keeping voltage, and these two signals are processed, then to floating boom driving circuit 8 sending control signal, simultaneously, this circuit is by adopting frequency jitter, the concentrated interfering energy that circuit is produced can be spread on wider frequency band, effectively reduces peak of radiation, improves the EMI characteristic of circuit; Floating boom driving circuit 8 is for driving the first power field effect pipe MOSFET1; Monitor signal for monitoring the drg trigger voltage of output and keeping voltage, and is sent into frequency jitter pulse-width modulation circuit 7 by voltage feedback circuit 9; The energy of afterflow limiting circuit 10 for storing in vent discharge magnetic coil after drg power-off; The magnet coil L that freewheeling circuit 11 is drg provides continuous current circuit.
This detailed description of the invention adapts to the input of global electrical network Width funtion, input voltage range is 75-265V (AC/DC), AC/DC universal, its load-carrying capacity can contain all hub type brakes in the market and block brake, maximum load capability can drive thrust to be the drg of 12000N, thus, four kinds of different voltage regulator control circuits are unified into one; Control circuit is in the scope of global electrical network Width funtion input regulation, the drg trigger voltage exported is 80V ± 1.5V (DC), the drg exported keeps voltage to be 20V-80V ± 2% (DC) continuously adjustabe, therefore, four of identical thrust kind of a drg can be integrated into one again, make in the past eight kinds of product simplifications become two kinds of products.
The principle of work of this detailed description of the invention: 1, control circuit energising (drg declutches): when input power connected by this control circuit, Switching Power Supply 6 works, sampling circuit 4, brake application time control circuit 5 and the second power field effect pipe MOSFET2 form a normally closed switch, when power-off not detected, the second power field effect pipe MOSFET2 is in conducting state always, frequency jitter pulse-width modulation circuit 7 produces the constant amplitude pulse sequence after modulation, the first power field effect pipe MOSFET1 is driven through floating boom driving circuit 8, the magnet coil L of drg obtains electric, feed back through voltage feedback circuit 9, frequency jitter pulse-width modulation circuit 7 pulse-width is modulated, the voltage on the magnet coil L of drg is made to remain on 80V ± 1.5V (DC), after approximately passing through 0.8 second, its feedback quantity of voltage feedback circuit 9 auto modification, voltage stabilization on the magnet coil L of drg is kept on voltage at the drg adjusted in advance, and (this keeps voltage to be adjusted by a potential device, recommendation is 30V-35V), under making drg remain on the state of declutching, till in time receiving brake application signal.
In the above process, freewheeling circuit 11 normally works, due to the second power field effect pipe MOSFET2 conducting, be equivalent to freewheeling circuit 11 and afterflow limiting circuit 10 parallel connection, afterflow limiting circuit 10 is by freewheeling circuit 11 short circuit, therefore, afterflow limiting circuit 10 is inoperative, the process that declutches of Here it is drg.
2, control circuit power-off (drg brake application): when this control circuit cuts off input power, Switching Power Supply 6 quits work, and frequency jitter pulse-width modulation circuit 7, floating boom driving circuit 8 quit work, and the first power field effect pipe MOSFET1 turns off; If there is no sampling circuit 4, brake application time control circuit 5 and second this link of power field effect pipe MOSFET2 in circuit, then the interior energy stored of the magnet coil L of drg still can maintain magnet stopper by freewheeling circuit 11 and be in attracting state, until the electric current of freewheeling circuit 11 drop to be not enough to maintain magnet stopper adhesive time till, drg time delay brake application can be caused thus, elevator time serious, can be made to slip car.
Sampling circuit 4 in this detailed description of the invention, brake application time control circuit 5 and the second power field effect pipe MOSFET2 are for addressing this problem and designing, when this control circuit energising work, sampling circuit 4, brake application time control circuit 5 and the second power field effect pipe MOSFET2 form a normally closed switch, when power-off not detected, second power field effect pipe MOSFET2 is in conducting state always, when cutting off input power, brake application time control circuit 5 turns off the delay time required for the second power field effect pipe MOSFET2 according to sampled signal and self memory function auto modification, and guarantee at 220V, under the different voltage of 110V, the identical drg brake application time can be obtained, once the second power field effect pipe MOSFET2 is turned off, freewheeling circuit 11 is just in high-impedance state and quits work, now, afterflow limiting circuit 10 is started working, so-called afterflow limiting circuit 10, as the term suggests be exactly the circuit of restriction afterflow branch current size, the energy stored in the magnet coil L of drg slowly can only be released by afterflow limiting circuit 10, branch resistance due to afterflow limiting circuit 10 is 1.5-3 times of the magnet coil L resistance of drg, so this leakage current far can not maintain the adhesive of magnet stopper, drg just discharges fast, complete brake application action, secondly, also because the utility model control circuit makes four kinds of drgs merge into one, the discreteness of magnet coil parameter is little, so the brake application time controling of drg is just more accurate.
This detailed description of the invention reasonable in design, adapt to the input of global electrical network Width funtion, AC/DC universal, load-carrying capacity is strong, achieve the unification of unification voltage regulator control circuit different from four kinds of interchange, direct current, 110V, 220V tetra-kinds of different braking devices, thus decrease product category, improve product and manufacture parsimony and the conformability of link, greatly reduce the warehouse cost of raw MAT'L and supply and demand both sides finished product, circuit performance is more reliable simultaneously, work more stable, there is market application foreground widely.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical personnels in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
