In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0032] A measurement information repeater, such as Figure 1 As shown, it includes a main processor module, a signal input interface circuit, a serial port output driver module, a display driver module, a display and a power module; the signal input interface circuit, the serial port output driver chip and the power module are respectively connected to the main processor module, and the main processor module is connected to the display through the display driver module.

[0033] like Figure 2 As shown, the signal input interface circuit includes a high-frequency transformer, a voltage regulating circuit, an optical coupling unit, and a communication input interface unit. The communication input interface unit is connected to the main processor module through the high-frequency transformer, the voltage regulating circuit, and the optical coupling unit in sequence.

[0034] like Figure 3 As shown, the power supply module includes a filter circuit, a DC / DC converter and a power supply voltage stabilization circuit. The filter circuit is connected to the main processor module through the DC / DC converter and the power supply voltage stabilization circuit in sequence; the filter circuit includes a resistor R9 and a capacitor C9; the DC / DC converter and its peripheral circuit include a voltage input VIN terminal, a resistor R1, a resistor R2, a resistor R3, a resistor R7, a capacitor C1, a capacitor C2, a capacitor C3, a capacitor C5, a capacitor C6, a capacitor C7, a capacitor C8, a capacitor C10, an inductor L1, a chip FR9885, and a voltage output VDCDC terminal;

[0035] Among them, the PWM end of the MCU processor is connected to one end of the resistor R9, the other end of the resistor R9 is respectively connected to one end of the capacitor C9 and one end of the resistor R7, and the other end of the capacitor C9 is grounded; the voltage input VIN end is respectively connected to one end of the capacitor C1, one end of the capacitor C2 and the VIN end of the chip FR9885, the other end of the capacitor C1 is respectively connected to the other end of the capacitor C2, one end of the capacitor C3 and the GND end of the chip FR9885 and grounded, the other end of the capacitor C3 is connected to one end of the resistor R1, the other end of the resistor R1 is connected to the SHDN end of the chip FR9885, and the BS end of the chip FR9885 The T end is connected to one end of capacitor C10, the other end of capacitor C10 is respectively connected to the LX end of chip FR9885 and one end of inductor L1, the other end of inductor L1 is respectively connected to one end of resistor R2, one end of capacitor C5, one end of capacitor C6, one end of capacitor C7, one end of capacitor C8 and the voltage output VDCDC end, the other end of capacitor C5 is respectively connected to the other end of resistor R2, one end of resistor R3, the other end of resistor R7 and the FB end of chip FR9885, the other end of resistor R3 is grounded, and the other end of capacitor C6 is respectively connected to the other end of capacitor C7 and the other end of capacitor C8 and grounded.

[0036] By adjusting its PWM module, a PWM wave with a variable duty cycle is generated. The filter circuit is composed of simple resistors and capacitors. The selection of resistance and capacitance values ​​depends on the first harmonic component of the PWM wave. In order to respond to the power request in time, the duty cycle of the PWM wave needs to be adjusted accordingly and the received power needs to be increased or decreased. The PWM output pin needs to be connected to the DC / DC feedback pin after passing through the filter circuit. It directly uses the PWM function module to control the output voltage divider feedback circuit of the DC / DC. It does not need to use a high main frequency, but only needs to generate a control signal to control the voltage regulation module to achieve accurate and reliable voltage regulation. It uses the LM2596-5 chip. Its power supply circuit has a wide input voltage range, stable output voltage, low power consumption mode and thermal shutdown current limiting protection.

[0037] like Figure 4 As shown, the serial port output driver module includes a low-voltage difference linear regulator, a waveform generating circuit, a level shifting module, a dead time processing circuit and a non-overlapping module, and a delay calibration circuit. The output end of the low-voltage difference linear regulator is respectively connected to the input end of the level shifting module and the input end of the dead time processing circuit and the non-overlapping module. The output end of the waveform generating circuit is connected to the input end of the dead time processing circuit and the non-overlapping module. The output end of the dead time processing circuit and the non-overlapping module is connected to the input end of the delay calibration circuit.

[0038] The present invention integrates dead time adjustment and non-overlapping modules in one. The non-overlapping function can strictly control the high-side power tube and the low-side power tube drive signals to output high levels at the same time, thereby preventing the two power devices from being turned on at the same time and effectively suppressing the high current shoot-through phenomenon. The dead time adjustment function can reduce the time that the drive waveform is simultaneously at a low level, thereby improving the conversion efficiency of the power supply system within the entire cycle.

[0039] The present invention suppresses the high-current shoot-through phenomenon of power devices by adjusting the dead-zone minimization processing module and the non-overlapping module, which helps to improve the efficiency of the power module and utilizes the high-frequency characteristics of gallium nitride devices to significantly increase the operating frequency of the power system.

[0040] like Figure 5 As shown, the dead time processing circuit and the non-overlapping module include a level comparison circuit, a non-overlapping processing module, and a bias circuit processing module. The bias circuit processing module is connected to the level comparison circuit through the non-overlapping processing module.

[0041] like Figure 6 As shown, the level shifting module includes a signal delay calibration unit and a shifting level processing unit, the level comparison circuit is connected to the signal delay calibration unit, and the signal delay calibration unit is connected to the shifting level processing unit.

[0042] The power module is one of the sources of efficient power. To further improve system efficiency, it is necessary to understand the system loss types of the power module and optimize the efficient drive system by analyzing the system's loss factors and loss size.

[0043] The present invention suppresses the high-current shoot-through phenomenon of power devices by adjusting the dead-zone minimization processing module and the non-overlapping module, which helps to improve the efficiency of the power module and utilizes the high-frequency characteristics of gallium nitride devices to significantly increase the operating frequency of the power system.

[0045] like Figure 7 As shown, the optocoupler unit includes an optocoupler U1, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor and a transistor V1. The IN1 input end of the optocoupler U1 is connected to one end of the second resistor through the first resistor, and the other end of the second resistor is connected to the +12V voltage end of the optocoupler U1. The positive output end of the optocoupler U1 is connected to the collector of the transistor V1 through the third resistor. The negative output end of the optocoupler U1 is connected to one end of the fourth resistor and one end of the fifth resistor. The other end of the fourth resistor is connected to the base of the transistor V1, and the other end of the fifth resistor is connected to the emitter of the transistor V1.
