This course is a high-quality teaching video on the principles and applications of inverters taught by Professor Li Jiusheng of Harbin Institute of Technology. The complete course has a total of 36 hours. The main circuit of the frequency converter is the power conversion part that provides voltage-regulated and frequency-modulated power to the asynchronous motor. The main circuit of the frequency converter can be roughly divided into two categories. The voltage type is a frequency converter that converts the DC of the voltage source into AC, and the filter of the DC circuit. It's a capacitor. The current type is an inverter that converts DC from a current source into AC, and its DC loop filter is an inductor. It consists of three parts: the "rectifier" that converts industrial frequency power into DC power, the "smoothing circuit" that absorbs the voltage pulsations generated in the converter and inverter, and the "inverter" that converts DC power into AC power.

Does the ARM chip have a serial number? Tracing the kernel code, I found that cat cpuinfo shows Hardware: Samsung-SMDK2410 Revision: 0000 Serial: 0000000000000000 Serial. It actually reads an SFR of S

When I was working on a project, I found that after the CC2530 terminal node joined the ZigBee network, the request frame was sent too quickly, less than 1s, which affected the operation of other part
1. Problem and GoalThe problem is the one we raised in JavaScript before , where we showed the front-end user verification done with JavaScript . We also saw that when we use the source code analyzer
