 Gate drivers play an extremely important role in modern power electronics systems. Today, MobikeChip takes an in-depth look at gate drivers to see what they are and how they play a key role in a variety of circuits.    Definition of a Gate Driver  A Gate Driver is essentially a circuit whose primary function is to enhance the gate signal of a Field Effect Transistor ( MOSFET ) or Insulated Gate Bipolar Transistor (IGBT). As we know, MOSFET and IGBT semiconductor switches in the electronic system is responsible for controlling the current on and off, but their gate signal is often weak, directly from the controller output signal is difficult to drive them efficiently and stably. And the emergence of the gate driver, the perfect solution to this problem. It is like a signal “translator”, the controller output low voltage, low current signal, into high voltage, high current pulse, so as to accurately control the gate of MOSFET or IGBT, greatly improving the performance...

 In modern electrical systems, current sensors , as a key electronic component, undertake the important task of accurately measuring current. Whether in the field of industrial automation, power systems, or in new energy vehicles and other emerging industries, current sensors play an indispensable role. Today, MobikeChip will provide you with an in-depth analysis of the working principle of the current sensor.   Electromagnetic Induction Current Sensors: Classical Application Based on the Law of Electromagnetic Induction  (A) Basis of operation  Electromagnetic induction current sensors work on the basis of Faraday's law of electromagnetic induction. When a current passes through a conductor, a magnetic field is generated around it. Electromagnetic induction current sensors indirectly measure the current by detecting changes in this magnetic field. A common type of induction current sensor is the current transformer, which consists of a primary winding and a sec...

 Liquid level sensors play a key role in many scenarios where liquid level needs to be monitored, whether it's a chemical storage tank in industrial production or a domestic water heater in daily life, it's indispensable. Today, MobikeChip will provide you with an in-depth analysis of the working principle of liquid level sensors. Buoyancy Level Sensors: Wisdom Application Based on Archimedes' Principle (A) Float Level Sensor  Float level sensor is one of the most common buoyancy level sensors. It mainly consists of a float, a connecting rod and a measuring device. According to Archimedes' principle, an object immersed in liquid is subjected to upward buoyancy, and the size of the buoyancy is equal to the gravitational force exerted on the object to displace the liquid. When the liquid level changes, the float moves up and down with it. For example, in a water storage tank, as the water level rises, the buoyant force on the float increases, the float will move upward;...

 Current-sense transformers play a key role in modern power systems and electronic equipment for accurate current monitoring and measurement. Today, MobikeChip will provide you with an in-depth analysis of the working principle of current sensing transformers, and take you to unravel its mystery.   The cornerstone role of the basic principle of electromagnetic induction   (A) Review of electromagnetic induction phenomenon  The work of current induction transformer is based on the important physical principle of electromagnetic induction. When there is a changing current in the conductor, it will produce a changing magnetic field around it, a phenomenon known as the magnetic effect of the current. Conversely, when a closed conductor loop is in a changing magnetic field, the loop will produce an induced electromotive force, which in turn forms an induced current, which is the phenomenon of electromagnetic induction. Current induction transformer is the clev...

 The risk of electrocution is always a major concern in the operation of all types of electrical equipment. As an important component of electrical safety, isolation transformers play a key role in preventing electrocution. Today, MobikeChip will provide you with a detailed analysis of how isolation transformers prevent electric shock.   The core principle of electrical isolation   (A) winding isolation mechanism  There is no direct electrical connection between the primary and secondary windings of the isolation transformer, which is coupled only by the magnetic field. This is its fundamental mechanism to prevent electric shock. When the human body comes into contact with the circuit on the secondary side of the isolation transformer, due to the absence of an electrical path between the primary and secondary, even if there is a leakage of the utility power connected to the primary side, the current can not be directly conducted to the secondary side thro...

 Buying the right isolation transformer is critical in the construction and maintenance of electrical systems. It is not only about the stable operation of the equipment, but also closely related to the safety of personnel, MobikeChip will provide you with a detailed introduction to the key points of the purchase of isolation transformers.   Isolation transformer BUY   Clear their own needs   (A) voltage level requirements  First of all, to accurately determine the required input and output voltage levels. Different electrical equipment requires different voltages to operate, for example, industrial equipment may need to convert high voltage utility to a specific low voltage, while medical equipment requires high stability and accuracy of the voltage. For example, in a common industrial automation line, if the rated operating voltage of the equipment is 220V and the local utility is 380V, you need to select an isolation transformer that can convert t...
