In DC-DC circuit design, ripple is an important reference indicator. Larger ripple will directly affect the normal operation of the circuit. Wrong testing methods will cause high-frequency noise with large amplitude to appear in the oscilloscope, while correct testing methods can greatly improve the results of ripple testing. Summary of content: How to judge the quality of a power circuit, how to measure ripple correctly, and use the Himalaya series MAX17503 development board for testing
I am far away in Shenyang, I wish you all a good dream in 2009, and then work hard to realize this dream, let us build a harmonious industrial control forum and create a space for common progress! Hah
The power supply circuit uses a 2596 switch chip. Because the product requires 3.3V to power the wireless module, I added a π-type filter between 5V and 3.3V to ensure the clean power supply of the wi
Variable frequency series resonance It is a device that changes AC voltage, current and impedance. When there is AC current in the primary coil, AC magnetic flux is generated in the iron core (or magn
