Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
5. Identifiers and keywords of C language
A complete PIC microcontroller C language program usually consists of six parts: include files (i.e. header files 1, variable definitions, variable de...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
Abstract: In recent years, with the establishment and grid-connected power generation of a large number of solar photovoltaic power stations at home and abroad, photovoltaic grid-connected inverter...[Details]
The power consumption of a switching power supply includes fixed losses caused by parasitic resistances such as semiconductor switches, magnetic components, and wiring, as well as switching losses ...[Details]

Some people think: as long as the program runs well, it doesn't matter how the original program is written. But this is absolutely not the case. Software is not completed in one go, and it is neces...[Details]
The number of timers/counters and interrupt sources directly determines the performance of the microcontroller. The MCS-51 microcontroller has two programmable 16-bit timers/counters and five inter...[Details]
This paper first proposed an elevator controller algorithm based on a finite state machine, and then designed a three-story elevator controller based on the algorithm. The correctness of the elevat...[Details]
In the industrial production process, flow measurement is a widely used measurement physical quantity. In special cases, such as vertical oil wells, when it is not easy to install probes outside the p...[Details]
With the development of my country's economy, environmental pollution caused by energy consumption is becoming more and more serious. Sulfur dioxide and nitrogen oxides emitted from coal-fired flue...[Details]
UPS is an uninterruptible power supply (UPS). This device can ensure that after a power outage in the computer system, users can continue to work for a period of time and save files urgently, witho...[Details]
Conventional crystalline silicon solar cells are made on high-quality silicon wafers with a thickness of 350-450μm, which are sawn from pulled or cast silicon ingots. Therefore, more silicon materi...[Details]
In the field of video surveillance, video compression encoding formats have evolved from M-JPEG, H.263, MPEG4 to H.264. Currently, H.264 is the mainstream compression algorithm. Its biggest advantage ...[Details]
