  • Intelligent Vehicle - MEMS Sensor Test Solutions
    In the past two years, car networking, autonomous driving, unmanned driving, and automobile intelligence have become hot topics in the automotive industry, and have also guided the future development direction of automobiles. The purpose is to further improve the safety, reliability and comfort of vehicles during driving. For example, traditional emergency braking is controlled by the driver. Once the driver is in a state of fatigue driving, it is prone to traffic accidents. However, autonomous vehicles with a higher level can automatically determine the safety distance from the left and right vehicles, respond in milliseconds, and reduce their dependence on personnel.

  • How to use the IT2800 SMU to quickly test the I-V characteristics of MOSFET devices
    MOSFET, short for Metal Oxide Semiconductor Field Effect Tube, is a common power switching device used in circuit design. It is a voltage controlled device. It is characterized by gate voltage to control the drain current and has the advantages of simple driving circuit, low driving power, fast switching speed, high operating frequency and higher thermal stability than GTR. According to the conductive channel power, MOSFET can be divided into P-channel and N-channel. According to the gate voltage amplitude, it can be divided into depletion type (when the gate voltage is zero between the drain and source, there is a conductive channel) and enhancement type (gate voltage is not zero when there is a conductive channel). Power MOSFETs are mostly N-channel enhancement type.

  • Forced discharge test of battery
    Effective January 1, 2009, the latest version of the Technical Instructions for the Safe Transport of Dangerous Goods by Air issued by the International Civil Aviation Organization (ICAO) added UN serial numbers for dangerous goods, and lithium batteries will be classified as lithium-ion batteries (UN 3090 and UN 3091) and lithium metal batteries (UN 3480 and UN 3481). The regulation states that lithium batteries cannot be transported by air if they do not come with a test report or certificate of approval based on UN38.3.

  • Grid-connected performance test of dynamic reactive power compensation devices in the wind farm.
    As the renewable resources has become more and more popular, the wind farm construction has been increasing in recent years. However, the electricity generated by wind power is usually unstable. Here, a reactive power compensation device plays an important role on regulating voltage, power factor, harmonics and stabilizing the power system.

  • Ideal power supply for AC motor
    An AC motor is an electric motor driven by an alternating current (AC).The impact of the motor's starting current may cause the output voltage of the power supply to drop or trigger the overcurrent protection, resulting in failure to start. After the AC motor is started, as the motor speed increases, the stator current will quickly stabilize and then work within the rated current range. If we use a power supply with very high output current just to avoid the impact of start current, it will increase the equipment cost at the same time.An effective method to solve the problem of the starting current is the soft start of the motor.
