Overview:
The new power electronics IGBT is the core component of the power converter, and its drive and protection circuits are critical to the reliable operation of the converter. The integrated drive is a self-contained independent drive board with the advantages of easy installation, high drive efficiency and reliable protection. It is the best way to drive and protect large and medium power IGBTs. The integrated driver generally includes four functional circuits such as on-board DC-DC isolated power supply, PWM signal isolation, power amplification, and fault protection. The functional circuits cooperate with each other to complete the driving and protection of the IGBT. The input power supply supplies power to each functional circuit on the primary side of the board. The two DC-DC isolated power supply outputs drive the upper and lower half-bridge switching tubes respectively, and provide power for the IGBT side fault detection and protection circuit. Therefore, the power supply on the integrated driver board is all. The premise and basis of the circuit work.

Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical property type and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
