Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]

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]

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]

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]

introduction At present, measuring instruments are developing towards networking, and each individual embedded instrument will become a node on the Internet. This system realizes the network...[Details]

For a long time, my country has implemented "community-style collective heating" for hot water heating, and settled accounts based on the heating area, regardless of whether the user uses heat. Thi...[Details]

Improving the coordination of material handling and internal transportation between departments in modern factories is an important measure to achieve full automation of production. Traditional mat...[Details]

Many industrial fields such as industrial automation, logistics, and smart grids require that machinery and products be safe and have passed functional safety certification. When developing machine...[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]

从制造过程开始，一直到所有的应用领域，极低功耗技术逐渐成为所有设计中必不可少的需求。对能源敏感的应用，特别是必须以单颗电池提供连续数小时运作时间的产品，更需要加入极低功耗设计概念。要满足这些要求，就必须整合微控制器，这不仅要瞭解电池特性，还必须深入瞭解为了达到连续使用10、15甚至20年却无须更换电池的目标，应该如何设计一款装置。 要在极低功耗条件下操作，就必须用全新的方法来看待这...[Details]

1 Introduction With the rapid development of the national economy, AC motors have played an extremely important role in industrial production. As the main traction motor in various industries,...[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]

“Productivity determines production relations, and the development of productivity determines the change of production relations”, yes, society is always full of changes, and advanced science and t...[Details]

1. What is the difference between the continuous output power and the peak output power of a power inverter? Continuous power and peak power differ in the meaning they express. Continuous...[Details]

Compared with traditional lighting fixtures, LED lamps do not need to use filters to produce colored light. They are not only highly efficient and pure in color, but also can achieve dynamic or gra...[Details]
