0 Preface The most basic principle of the laser ranging system is to measure the time interval of the laser pulse propagating in space, so as to obtain the measured distance. This paper studies the...[Details]

introduction The power supply system supplies power to the accelerator, including a DC-200~-350kV 60mA main power supply, a 30kV 100mA power supply and a 10V 3A filament power supply, of w...[Details]

1. Startup process Let's briefly introduce the startup methods in two ways: Nor startup and Nand startup. Nor Start When using Nor boot, the base address of NorFlash is 0 and the on-chip RAM addr...[Details]

1. Introduction The parallel active power filter is a power electronic device that compensates for harmonics in the power system. Its main structure is divided into four parts: harmonic detection, PW...[Details]

Many toothpastes contain sodium fluoride, a fluoride compound, to prevent tooth decay. However, fluorochemicals have other unexpected uses. Researchers at the U.S. Department of Energy's Argonne Nati...[Details]

In the case of Micron suing Taiwan's wafer foundry giant UMC for indirectly assisting Jinhua in stealing DRAM processes, the Taichung District Court of Taiwan recently made a ruling: the three UMC ex...[Details]

The function signal generator system is mainly composed of a master oscillator, a master oscillator output adjustment potentiometer, a voltage amplifier, an output attenuator, a power amplifier, an i...[Details]

__main() and main() (reprinted) Because we usually have done a relatively detailed initialization work in BOOTLOADER, including the transfer of code, so we'd better not call the library function __ma...[Details]

Using a microcontroller to decode infrared remote control is a very troublesome problem for most beginners. The following is a C51 program for infrared remote control decoding that I wrote myself, ...[Details]

In the last EV Focus column, we talked about why electric vehicles need to use 800V, and also roughly understood the relationship between SiC and 800V. In this issue, we will zoom in and talk about...[Details]
