This controller uses PIC16C54 single-chip microcomputer as the controller, and it is very easy to use: just connect a telephone line to the loudspeaker through the controller, and you can rem...[Details]
The rectified DC voltage is then converted back to AC using power electronics such as insulated gate bipolar transistors.
The output voltage is switched on and off at a high frequency, control...[Details]
1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]
Stepper motors, also called steppers, use the principles of electromagnetism to convert electrical energy into mechanical energy and have been used since the 1920s. With the increasing popularity o...[Details]
I. Introduction
The use of electronics in cars dates back to the early 20th century when electric starters replaced hand cranks. Automotive electronics became popular in the 1960s with the...[Details]
1 Causes of problems with electric vehicle batteries
1.1 Caused by the battery itself
Why do we say that? In the previous issue, we learned about the working princi...[Details]
Lithium iron phosphate batteries are used as lithium-ion secondary batteries. Their main application is now in power batteries, which have great advantages over NI-H and Ni-Cd batteries.
Lithi...[Details]
With the continuous development of integrated circuit technology, integrated circuits have developed from thousands of gates to the current level of millions and tens of millions of gates. The applica...[Details]
PID is proportional differential adjustment. You can refer to the detailed introduction in the automatic control course for details! The positive action and the negative action in temperature contr...[Details]
When designing a PLC system, the control scheme should be determined first, and the next step is to select the PLC engineering design. The characteristics of the process and the application require...[Details]
1 Introduction
The early stage control system used relay control. Due to the large number of stage equipment, the number of control elements is huge and the wiring is complicated. Therefore, th...[Details]
