Working principle

The workflow of the entire diode and gate drive circuit system revolves around "energy conversion+precise control", and the core principles are as follows:

1. Energy preprocessing: AC input electrical energy is converted into DC electrical energy through a diode rectifier circuit (partially supported by the built-in diode of the 5SHY module). The diode prevents the reverse flow of current through its unidirectional conductivity and provides a freewheeling channel when the power device is turned off, stabilizing the circuit voltage.

2. Signal control: The 3BHB021400/3BHE019719R0101 control board receives control instructions from the upper computer (such as PLC), combines the sampled signals of current, voltage, temperature, etc. in the circuit, and generates driving control signals that meet the requirements through internal chip processing.

3. Gate Drive: The GVC736BE101 gate drive module amplifies the weak signal output by the control board, and outputs a+15V on voltage and a -10V off voltage to the gate of the 5SHY series IGBT. When the gate obtains a forward voltage, the IGBT conducts and converts DC electrical energy into AC electrical energy of the desired frequency through the IGBT; When the gate obtains a reverse voltage, the IGBT is turned off and the conversion process is paused.

4. Fault protection: If the circuit experiences abnormalities such as overcurrent (such as load short circuit), overheating (such as poor heat dissipation), etc., the control board will immediately detect the abnormal signal, and the driving module will quickly cut off the gate driving voltage, while triggering an alarm signal to ensure the safety of the entire system.

Precautions

-Installation specifications: Before installation, it is necessary to confirm that the product model matches the circuit requirements. The IGBT module should be tightly attached to the heat sink and coated with thermal conductive silicone grease to ensure heat dissipation effect; When installing the control board and drive module, it is necessary to avoid metal impurities entering the interface, and the torque of the fixing screws should meet the manual requirements (usually 2-3N · m).

-Electrical safety: Before wiring, the main power supply and control power supply must be cut off to ensure that the capacitor is completely discharged (discharge time not less than 5 minutes); The high-voltage circuit and low-voltage control circuit need to be wired separately, with a distance of not less than 5cm, to avoid electromagnetic interference.

-Parameter setting: Before the first use, it is necessary to debug the interface through the control board, set the driving frequency, protection threshold and other parameters according to the load characteristics, and prohibit arbitrary modification of default parameters to avoid affecting performance or causing faults.

-Maintenance requirements: Regularly (recommended every 6 months) check the cleanliness of the heat sink, remove dust and oil stains; Check if the wiring of the module pins is loose and if the insulation layer of the drive cable is damaged; If there is a malfunction, it must be detected by professional personnel using specialized equipment, and non professional personnel are prohibited from disassembling.

-Storage conditions: Unused products should be stored in a dry environment with a temperature of -40 ℃~+85 ℃ and a humidity of ≤ 85%, avoiding direct sunlight, rain, and chemical corrosive gases. The storage period should not exceed 12 months, and performance testing should be repeated if exceeded.
