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.

Hello everyone, I am using sqlite database, but I found that it does not support Chinese paths, but I want to put the data on the memory card, how can I solve it? I found that it may be a problem with
This video introduces a simple method to estimate the transient response of a power supply by understanding the control bandwidth and output filter capacitor characteristics. This method takes advanta
If the resonant inductance of the primary side can be replaced by the leakage inductance of the transformer, then there is no need for an external inductor. How do we calculate the inductance paramete
A few days ago, as soon as the event came out, I went to watch the video to learn. I took notes while watching the video. The main reason was that I was afraid that I would have to go to Baidu again d
1. First, use IAR as IDE. Of course, it is not appropriate to call it a compiler. It is more reasonable to call it IDE. Let's call it that for now. 2. Please understand the __low_level_init() function
