thereby controlling external devices or circuits.
Driving voltage: The gate voltage of MOSFETs and IGBTs is usually between 10V and 15V, but the output voltage of the gate driver should be greater than this range to ensure reliable conduction and cutoff of the device. The output voltage range of gate drivers is usually determined based on specific applications and device requirements.
Drive current: In order to charge and discharge the gate capacitance of MOSFETs and IGBTs, the gate driver needs to provide sufficient current. These current values typically range from a few hundred milliamps to a few amperes, depending on the size
of the device”s gate capacitance and switching speed requirements.
Drive speed: The gate voltage of MOSFETs and IGBTs changes rapidly, so the gate driver must be able to quickly charge and discharge the gates of these devices. The speed of driving directly affects the switching speed and efficiency of the device.
Anti interference capability: In the application environment of power electronics, there are various electromagnetic interferences and noises. The gate driver must have a certain anti-interference ability to ensure the reliability and stability of the signal.
Main components
The gate driver mainly consists of the following parts:
Power supply: usually composed of a DC/DC converter and a capacitor. DC/DC converters convert input voltage into output voltage suitable for gate drivers (typically between 15V and 30V), while capacitors are used to store charge for fast charging and discharging of MOSFET and IGBT gates when needed.
Amplifier: The core component of a gate driver that converts input signals into drive signals suitable for MOSFET and IGBT gates. An amplifier typically consists of transistors, operational amplifiers, and inverters/non inverters, used to amplify input signals and control the current of transistors.
Protection circuit: used to protect MOSFETs and IGBTs from damage. Protection circuits typically include functions such as undervoltage protection, overvoltage protection, overcurrent protection, and transient voltage protection to prevent device damage caused by abnormal power supply voltage or excessive output current.
Output circuit: Convert the output current of the amplifier into driving signals suitable for MOSFETs and IGBTs. The output circuit typically consists of a driving transformer and an output capacitor, used to convert the driving signal into a voltage suitable for the gate and store charge.
responsible for processing signals from on-site sensors or driving actuator actions. For example, they may need to cooperate with devices such
as BANNER travel switch T30UIPB to receive their transmitted position signals; Or by controlling components such as Burkert solenoid valve 00131421, the on/off of fluid media can be precisely managed.
these modules integrate more complex logic processing capabilities. The core task of a pressure switch is to detect whether the pressure
has reached a preset threshold and output a switch signal. Its function is highly specific and fixed. And modules 5X00501G01 and 1
C31219G01 have the ability to comprehensively judge multiple such switch signals and transmitter signals (such as transmitter 1066-P-HT-60),
and output complex control instructions according to internal logic.
