Click the above Computer Enthusiasts to follow us Do you experience eye fatigue and dryness when using your phone for extended periods? Do you also suffer from migraines triggered by long gaming sessions? If your phone screen happens to be OLED (including AMOLED), it is likely due to a dimming scheme called “PWM”. The New … Read more
Focus on “Jicheng Training”, specializing in automation education for 14 years It is generally believed that the inverter output voltage is 380 volts, and direct measurement should not be a problem. However, in reality, most multimeters cannot obtain correct readings when testing the inverter output voltage, and in some cases, the multimeter may even burn … Read more
Design Case (40mm Annular Control Board) This application design simplifies and optimizes the sensorless control algorithm for Brushless Direct Current (BLDC) motors, which is typically implemented by Digital Signal Controllers (DSC) or high-end 16/32-bit microcontrollers. It achieves complete control functionality on the New Tang enhanced 1T 8051 core microcontroller, highlighting the overall cost-performance ratio of … Read more
Understanding Analog and Digital Signals in Electronics In the previous content, we talked about digital output driver circuits. Digital quantities are a type of boolean variable that has only two states. Here, let’s discuss analog quantities. For a lamp, we can describe its two states—on and off—using digital quantities. Turning the lamp on means it … Read more
3. BCM System Composition and Control Principles The Controller Area Network (CAN), Local Interconnect Network (LIN), and FlexRay are commonly used automotive buses. The CAN bus is a serial multi-master controller real-time control local area network bus, with synchronous information transmission. The physical layer is a single wire; the architecture consists of one master device … Read more
I have been busy with final exams for a while, and I apologize for the delay. In this chapter, we will continue from the last section that we didn’t finish. After getting the PCB soldered, we need to program this chip. Main Content First, let’s take a look at the actual photo after soldering. Let’s … Read more
Research Content As part of electric vehicles, motors and controllers are usually mass-produced. To reduce costs, controllers typically adopt modular components for assembly, facilitating automated production, testing, and maintenance. Reducing the number and variety of parts can also lower inventory and management costs. A 600 V/36 kW/5600 rpm permanent magnet synchronous motor controller has been … Read more
