How to convert alternating current to direct current? In other words, what is the easiest way to output the 220v alternating current of the general household circuit as direct current? Thanks!

Is there any was to use an off-line switcher to take input of 90-200VAC @ 250-500HZ? When I try this with the above part I get a lot of jitter on the input source signal I am also trying to measure.

In an off-line switch, is the GND generated has a floating / drifting component to it? I am taking the AC source before the Half Bridge and dividing down to measure the amplitude and frequency. I find that the AC varies a lot in amplitude which causing jitter in frequency

Hello, I have attempted to create a flyback design with multiple outputs each with a unique ground. One of the main issues I'm facing is when there are strong step loads on either secondary winding and then removed, I can read as much as 33V on my 24V rail. The

My microcontroller drives IRF3205, it can drive but the led light is not too bright, it is the same with a 12v power supply, please tell me why? Can you give a simple circuit? The transistor of C9014 can amplify the signal of the single-chip microcomputer and then 3205?

Hello all, We are designing a DC-DC converter using LNK3207 with the following design parameters: Vin: Either 48V(40Vmin and 58V max) or 72V (63V min and 80V max) battery pack Vout: 25V Max current output: 0.5A Query 1: The min. voltage given in the corresponding datasheet is 70V at full

Hi, I am designing a 15W 5V SMPS Board for a universal line voltage input (85V-265V). Most of the design works well but I am seeing a lot of High-Frequency Ripple on the Output of the SMPS PCB. See the attached Schematic and Waveforms for the measurements and design. Please

Hello, all I bought a LED driver: input: AC100-240V Output: DC30-57v / 600mA (constant) I connected it to a led strip, they flashed several times then switched off (i suspect they died, so i check the LED Driver Failure Analysis and Maintenance to detect), then took the multimeter and measured

Can someone help me on what is the difference between the TNY288DG-TL & TNY288DG0246-TL And also what is the meaning of the suffix 0246 on the MPN. Thanks
