This is a low-cost isolation achieved through a power transformer. Since the transformer is more convenient for AC isolation, but DC is not suitable, ATtiny412 is specially used for control.
Design features: Bus power evaluation, quick and easy testing of different bus power filters, configurable module application for master or slave, DC blocking bus capacitors, onboard receiver/transmitter enable/disable pull-up/pull-down resistors
A simple power supply design based on USB-PD, USB-PD allows to provide voltage up to 20V (current up to 5A), the author shared his design details, you can have an in-depth understanding of the working principle of USB-PD.
The CircuitSetup Split Single Phase Energy Meter is an affordable, accurate remote energy monitoring device for your entire home. It monitors energy usage in real time, independent of power company meters, and can be easily connected to any wireless microcontroller (such as ESP8266 or ESP32) to transmit energy data to programs such as EmonCMS. It can also be used to monitor solar systems to track the amount of electricity you generate from the sun. It uses a secure current transformer clamp to sample current - no AC wiring required.
makerPower Solar is a smart solar battery charger and 5 V power supply combination. It allows technology professionals and enthusiasts to take their embedded systems and IoT devices off the grid and run them anywhere. It can operate as a simple stand-alone power supply or as a peripheral capable of comprehensive reporting of power conditions. True Maximum Power Point (MPPT) algorithms extract every joule of energy from all solar conditions.
You can certainly buy desktop power supplies, but they're not cheap. As the current capacity and output voltage quantity increase, so does the price. While a commercial desktop power supply is certainly worth the investment, you may want to consider a cheaper solution. Adapt an old computer power supply for use on your workbench. Computer power supplies have all the voltages you need and some very impressive current capabilities.
This 45W Type-C PPS reference design uses Infineon's EZ-PD™ PAG1s and PAG1P controllers and CoolGaN™ 600V GIT HEMT.
