Five. embodiment
What accompanying drawing provided is electrical schematic diagram design parameter, is not limited to above-mentioned electrical schematic diagram circuit and parameter value in practical application.
Power transformer exports AC24V-30V voltage, through D1-D4 bridge rectifier circuit, then through C1 and C2 filtering, be input to 317 regulating circuit IC1, for preventing connection terminal short circuit, the B+ connection terminal of regulator A to be tested, is connected with 317 regulating circuit IC1 by resistance R2.According to regulator actual working state, be connected by resistance R3 at B+ terminal with L terminal, simulation generator L terminal exports.
In actual application, the regulator A tested need first be selected to be that 14V series or 28V are serial? interior bonding or external earth? such as: the electrical schematic diagram for bonding regulator in test 14V provided in accompanying drawing.
In actual application, available single-chip microcomputer model has a lot, such as: AT89C2051 single-chip microcomputer.
When 317 regulating circuit IC1 output voltages are too high, higher than regulation voltage, the F pole of tested regulator A is by output low level, VT6 is in cut-off state, G5 will be high level, single-chip microcomputer will by programming Control G1-G4, reduce 317 regulating circuit IC1 voltage sampling resistors, thus reduce 317 regulating circuit IC1 output voltages, otherwise, when 317 regulating circuit IC1 output voltages are too low, single-chip microcomputer will by programming Control 317 regulating circuit IC1, make it output voltage to raise, finally tend towards stability state, 317 regulating circuit IC1 both end voltage are the regulation voltage level of tested regulator A, presented by voltage table, regulator potentiometer R34, with the error that last trading day R2 causes, the F terminal lifting frequency of regulator regulator A, amplify through power amplifier IC3, the sound is sent by loudspeaker LB,
Principle according to this, when switch K1 is connected with right side circuit, can test external earth regulator, when switch K2 is connected with right side circuit, can test 28V regulator.
For the regulator of some bands P terminal, if and only if, and P holds frequency to be more than or equal to 120HZ, when P terminal voltage is more than or equal to 3V, regulator can normally work, therefore, singlechip controller IC2 also must export 120HZ, 3V signal to the P terminal of regulator A (note: concrete P holds response frequency and voltage should determine according to the regulator of actual production).
For improving the accuracy of test result, 8 (or more than 8) single-chip microcomputers can be adopted, with controlling resistance 1 Europe for step-length, then 8 Single-chip Controlling resistance ranges are 1-255 Europe, the parameter provided with reference to the accompanying drawings, the corresponding 1.25V in 200 Europe, then singlechip controller IC2 controls the output voltage precision of 317 regulating circuit IC1 is 1.25V/200=0.00625V, and range of regulation is 255*0.00625V=1.59V.Regulate R31, make tester idle voltage output be 14.50V, so, it is 14.50 ± 0.8V that tester can test regulation voltage level, compares regulation voltage level industry standard 14.50 ± 0.5V scope wider.
According to " regulator regulation voltage static tester " that such scheme makes, through practice test, most 14V series, serial, the interior bonding of 28V, external earth, single function, multi-functional, the regulator such as three lines, four lines, five lines can be tested, instrument is after school is true, test result self-consistentency is good, need not often calibrate, need not temperature compensation correction, test operation is convenient, and test result is accurate.
