I saw in the book that when designing a switching power supply, some parameters or formulas are only applicable to the continuous conduction state. Generally, whether the switching power supply is in ...
Title: Drive the digital tube to display dynamically, and move from right to left on 8 digital tubes and display the number "2019" cyclically. Use the toggle switch or key as the external interrupt re...
When the player speed increases, the sound becomes higher. This is because the spectrum of the electrical signal becomes wider. But why does the spectrum of the sound become wider? Please give me some...
When CPLD is used as a DSP peripheral, DSP puts the data in the IO space, CPLD reads the data, and controls the peripheral operation program according to the corresponding address and information. I w...
It took about 20 days from application to review and then to receiving the board. During these 20 days, I have been thinking about how to design this set of products. Now I finally got it and started ...
Hardware designers have begun to adopt FPGA technology in high-performance DSP designs because it can provide 10-100 times faster computing than PC-based or microcontroller-based solutions. Previou...[Details]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
