Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
In a specific embodiment of the invention, the invention provides a relay response compensation circuit with adjustable time sequence, which comprises a MOS tube Q1, a rectifier diode Q2, a resistor R2, a resistor R3, a voltage regulator tube V1, a resistor R4, a resistor R5, a resistor R6, a magnetic latching relay K1, K1-1, K1-2, a resistor R1 and a capacitor C1.
The on or off of the MOS transistor Q1 can control the output of the output 1; the rectifier diode Q2 has a confluence function, and can combine the current of the original output 1 to the output 2 when the Q1 is turned off; the resistor R2, the resistor R3 and the voltage regulator tube V1 form a driving circuit of the Q1; the resistor R4, the resistor R5 and the resistor R6 divide the reference voltage to generate different reference signals; k1 is a magnetic latching relay with two sets of coaxial contacts, wherein K1-1 is used for the driving circuit of Q1, and when the K1-1 switch is on the left side, the driving circuit of Q1 can work normally; when the K1-1 switch is to the right, the drive circuit for Q1 is off. K1-2 is used for switching of reference signals. When the K1-2 switch is on the left, reference signal 1 is fed into the power conversion module; when the K1-2 switch is on the right side, reference signal 2 is fed into the power conversion module. Reference signal 1 ═ reference voltage × (R5+ R6)/(R4+ R5+ R6); reference signal 2 ═ reference voltage × R5/(R4+ R5); the resistor R1 and the capacitor C1 form a response compensation circuit of the relay, and the charging and discharging time of the RC circuit can be adjusted through different resistance values and capacitance values so as to change the response time of the action of the contact of the relay.
The working mechanism is as follows:
when the K1 switches are on the left side, the driving part where the K1-1 is located works normally, the Q1 is conducted, and both the output 1 and the output 2 can output; the reference circuit part where K1-2 is located sends a reference signal 1 to a power conversion module, and controls the actual output to be a value corresponding to the reference signal 1; when the K1 switches are on the right side, the driving part where the K1-1 is located does not work, the Q1 is disconnected, the output 1 has no output, and the output 2 has normal output; and the reference circuit part where the K1-2 is located sends the reference signal 2 to the power conversion module, and controls the actual output to be a value corresponding to the reference signal 2. R1 and C1 are response compensation circuits of the relay, for the coaxial contacts K1-1 and K1-2, the switching action of the two groups of contacts has certain time delay, if the switching speed of K1-2 is faster than that of K1-1, when the corresponding compensation circuit is not added, the K1 acts, the reference switching is firstly carried out, and then the output 1 is switched off; when the output 1 is required to be turned off and the reference is switched simultaneously, proper values of R1 and C1 can be selected, and the switching of the reference signal is slowed down through the charging and discharging action of the RC circuit; when it is required to turn off the output 1 first and then perform the reference switching, the values of R1 and C1 can be increased to greatly slow down the switching operation.
The circuit can compensate the switching response speed of the relay contact; meanwhile, the switching time sequence of a plurality of groups of coaxial contacts can be adjusted; the circuit can effectively simplify the design of a power supply product and realize complex switching by using fewer relays.
