- Stereo speaker level input to line level mono output converter
I am trying to connect an amplifier with 100W RMS per channel output to a subwoofer that only has a single channel line level input The amplifier does not have a volume controlled line preamp outp
- power electronics - Flyback transformer size vs. core losses . . .
Because the geometry (shape) is kept, so are all the proportions, the magnetic path length will increase x4 and the magnetic material cross-section will increase x16, i e all lengths increase by the same amount and the resultant volume increases x64 The inductance factor will increase x4:
- power electronics - How do buck regulator modules with integrated . . .
Looks like most of the volume of the converter is the inductor They need a certain volume of ferrite and more space for the copper winding to meet specifications (saturation current, inductance and DCR, for example) Usually the cost is much, much lower if you can afford the space If cost is of no concern you can use whatever you like
- High to Low logic level converter with MOSFET
I'm designing a sniffer circuit to tap input signals from various machines The type of signal varies from input pulses and UART communication, the voltage varies from 5V to 12V These are the
- How bad of an idea is it to use an AC transformer for a DC-DC converter?
However, the term fly-back transformer is also commonly used Because the coupled inductor in a flyback converter is designed to store energy, it often has either an physical "air" gap in the core (which is actually often filled with a solid material to reduce stresses and vibrations) or a "distributed air gap"
- Connection between TL431 Compensator and Controller in Flyback Converter
Below is my schematic for a flyback converter where I have chosen the UC3843 (datasheet) for my controller I've designed a secondary-to-primary feedback network using the TL431 I've implemented
- How to reduce audio noise from Bluetooth module
For this particular BT MP3 module, when using USB the noise is very low and almost inaudible at mid to high volume (The amp has it's own volume control), but when using BlueTooth the noise is so loud that it renders the whole thing unbearable
- Synchronous buck converter using STM32 as feedback controller
I am planning to use stm32f103cbt6 MCU as a feedback controller (voltage or current) for a synchronous buck converter by using gate driver IC, mosfets, inductor, capacitor and etc Is there any con
