This article gives you a talk about the half-bridge driver chip wireless charging, and the working principle of the half-bridge driver chip corresponding knowledge points, I hope to help you, do not forget to collect this site. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, The oxygen sensor fails before starting, and if it is not broken and does not need to be replaced, is there any other reason why it does not work?
1, the reason is that there is no voltage mutation during the switching process, the short circuit during the switching process of the output, only a gradual conversion between the step-down and boost modes. Almost not affected by temperature, dust and other environmental factors, the imitation peak current mode control scheme in order to ensure that the output voltage can be adjusted in a wide input voltage range, (2) then the frame ID can be read from the receive buffer identifier register, the PWM current mode control scheme must be used.
2, start difficult, refueling sensor (English name: transducer/sensor is a detection device that can feel the information being measured, and can transform the felt information into an electrical signal or other required form of information output according to a certain law to meet the requirements of information transmission, processing, storage, display, recording and control. The characteristics of the sensor include: miniaturization, digitalization, intelligence, multi-function, systematization and networking.
3, for example, you can ask whether the fault occurred in the engine or the transmission; If it is an engine, you can further understand whether it is an electrical fault or a mechanical fault; If it's a mechanical failure you can tell if it's a crank link or a valveAgencies, etc., and it's much easier to make a further diagnosis. After the fault is identified, it is easy to eliminate and repair.
4, indicating that the oxygen sensor has no real fault, so the failure light of the oxygen sensor is off after cleaning. Today's cars have two oxygen sensors, one before and one after a three-way catalytic converter. The role of the front oxygen sensor is to detect the air-fuel ratio of the engine under different working conditions, and the ECU computer adjusts the fuel injection amount and calculates the ignition time according to the signal.
5, the general engine fault light is on, he is likely to burn the state is not particularly good, the general state of the engine is not good, is the engine failureThe main reason for the amount of lights. There is also a guarantee that the engine will also cause a fault light, such as the car is weak, and the engine noise is too large, or there is an obvious knocking sound. So do some regular maintenance and repairs.
6, the main reason for the common engine failure throttle often dirty throttle dirty carbon deposit is that the engine in the working stroke when the air intake and exhaust gas reciprocating motion, not only in the intake will absorb air will also be in the valve overlap when the gas back into the intake port resulting in the formation of carbon deposit. In addition, the forced ventilation of the crankcase in front of the throttle gate will re-introduce the exhaust gas in the crankcase through the intake valveIs 25Q128 made in China?
1, xt25q128 is provided by Shenzhen Aixing Technology Co., LTD. Founded in 2017, Eiching Technology focuses on set-top boxes, motor drives, wireless charging solutions and other fields.

Variable-frequency Drive (VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control AC motor by changing the working power supply frequency of the motor. The inverter is mainly composed of rectifier (AC to DC), filter, inverter (DC to AC), brake unit, drive unit, detection unit and micro-processing unit.
Frequency converter is a power electronic device used to control the speed and torque of an electric motor. It controls the operation of the motor by changing the frequency and voltage of the power supply. Inverter can be divided into the following categories: low voltageInverter: Suitable for low power motors, usually between 0.4 kW and 500 kW. Medium voltage inverter: Suitable for medium power motors, usually between 500 kW and 10 MW.
Inverter, as the name suggests, is a device that can change the frequency, it is an AC power supply that can adjust the output of the frequency and voltage, mainly used for speed regulation of the asynchronous motor. Usually, the device that converts the power frequency alternating current with fixed voltage and frequency into the voltage or frequency variable alternating current is called "inverter".
Inverter (Inverter) is a frequency that will be fixedPower regulation equipment that converts rate alternating current to variable frequency alternating current. Also known as AC variable frequency governor, it is widely used in various fields because it can change the output voltage frequency and ensure stability and accuracy. It is involved in many industries such as industry, electricity, transportation, oil and natural gas.
