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.

I graduated with a master's degree this year, and moved to Wuhan, Chongqing, and Chengdu. Finally, I worked in scientific research in an institution in Chengdu. I feel very lucky. Thank you, Chengdu.
Tonight I randomly integrated the official SD card code into fatfs and made a simple video player. It seems to be quite effective. The SPI polling method does not use DMA, and the frame rate can reach
Use F021.h API to operate fbank. The chip is TMS570LS3137. Bank1 and bank7 can read and write, but bank0 Fapi_setActiveFlashBank(Fapi_FlashBank0); this code will get stuck. Does anyone know? :)

In July 2009 , Mitsubishi Motors Corporation's electric vehicle "i-MiEV" was equipped with Nichicon's "charger-integrated DC-DC converter", which is a device for charging the high-voltage and low-volt
