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.

The 12VDC signal controls the on and off of the 24VDC relay. I want to use a MOS tube to drive it. Is there any economical and small MOS tube to recommend? If there is any other better solution, pleas
I spent two schematics at the beginning, and after I finished drawing the PCB, the schematics looked a bit messy, so I divided the schematics into several more according to the functions. However, I f

For an npn tube, Iceo is a reverse cutoff current. C and E are both N. Where does the reverse come from? What does the reverse here mean? Does the actual direction of this current flow from C to E or
