In a specific embodiment of the invention, the invention provides a time sequence adjustable relay response compensation circuit which comprises a MOS tube Q1, a rectifying diode Q2, a resistor R3, a voltage stabilizing tube V1, a resistor R4, a resistor R5, a resistor R6, magnetic latching relays K1, K1-2, a resistor R1 and a capacitor C1.
The on or off of the MOS tube Q1 can control the output of the output 1; the rectifying diode Q2 has a confluence function, and when the Q1 is turned off, the current of the original output 1 can be combined to the output 2; the resistor R2, the resistor R3 and the voltage stabilizing tube V1 form a driving circuit of 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 groups of coaxial contacts, wherein K1-1 is used for a driving circuit of Q1, and when a K1-1 switch is on the left side, the driving circuit of Q1 can work normally; when the K1-1 switch is on the right, the drive circuit for Q1 is turned off. K1-2 is used for switching the reference signal. When the K1-2 switch is on the left side, the reference signal 1 is fed into the power conversion module; when the K1-2 switch is on the right, the 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 relay contact action.
The working mechanism is as follows:
when the K1 switch is on the left side, the driving part where the K1-1 is positioned works normally, Q1 is conducted, and both the output 1 and the output 2 can be output; the reference circuit part where K1-2 is located sends a reference signal 1 into the power conversion module, and the actual output is controlled to be a value corresponding to the reference signal 1; when the K1 switch is on the right side, the driving part where the K1-1 is positioned does not work, Q1 is disconnected, the output 1 is not output, and the output 2 is normally output; the reference circuit part where K1-2 is located sends the reference signal 2 into the power conversion module, and the actual output is controlled to be the 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, certain delay exists in the switching action of the two groups of contacts, if the switching speed of the K1-2 is faster than that of the K1-1, when the corresponding compensation circuit is not added, the K1 acts, the reference switching is performed first, and then the output 1 is turned off; when the output 1 is required to be turned off and the switching reference is performed simultaneously, proper values of R1 and C1 can be selected, and switching of the reference signal is slowed down through charge and discharge actions of an RC circuit; when the output 1 is required to be turned off first and then the reference switching is performed, the values of R1 and C1 can be increased, so that the switching action is greatly slowed down.
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 power supply products and realize complex switching by fewer relays.
