PowerDiagramGenerator is a lightweight and user-friendly program for computing or visualizing the power/voronoi diagram of the input (weighted) point cloud, to facilitate subsequent tasks such as rendering or reconstruction. This program primarily relies on CPU-based computations. The data structures used in this program are partially derived from:
5 Νοε 2019 · Here is a low-ripple and low-noise 48V regulated phantom power supply for an audio preamplifier and driver. Such power supplies require well-filtered, low-ripple and low-noise output voltage with current less than 200mA. These are relatively rare and expensive.
7 Μαρ 2020 · The circuit below is a basic 12 volt phantom power supply that can be constructed in several hours by an electronics hobbyist. It consists of parts commonly available from Mouser or Digikey. This circuit will provide 5 milliamps of phantom power and is designed to operate an electret condenser microphone.
This reference design delivers a 48-V output, low-noise power supply for the phantom power application using the TPS61391 and TPS7A4101 devices. The TPS61391 is a 700-kHz PWM step-up converter that converts. 3.3 V or 5 V to 48.5 V. The TPS7A4101 is a 50-V tolerant input and 0.29-V drop LDO that steps 48.5 V down to.
schematic of a typical phantom-powered electret microphone is shown in Figure 2. Resistors R8 and R9, combined with Zener diode D1, create a simple voltage regulator, dropping the 48-V phantom power to around 5 V to power the op amps in the microphone.
11 Νοε 2017 · I'm a student in electronics and I want to build a solid 48V phantom power supply for practice. But i also wanted to do one that would be useful at the studio. I've searched google and found some, most using a TL783 as regulator and some with BC546 or other npn to raise the power from a lower input.
Anyone involved with audio will know about phantom power, also sometimes known as P48, because the source voltage is (or is supposed to be) 48V DC. The term 'phantom' comes from the lack of any on-board power supply (such as a battery), and the power is delivered seemingly by magic.
