FAQS 4

What is the best portable power supply for college electrical engineering students?

The No Inductor power supply. This project utilizes PicoPD's previous work to prototype a bench power supply. Beside portable soldering iron, this should be one of the best portable tools for college electrical engineering students. This bench power supply is powered by USB-C PD 3.0/3.1 using their PPS capability.

What is SMPS power supply?

SMPS stands for switch mode power supply and it's the modern and most compact/efficient way of acquiring low voltage DC from mains AC source. However making an SMPS at home may not be as simple as making power supply units using traditional iron core transformers.

Does the bench power supply have a buck or boost converter?

This bench power supply is powered by USB-C PD 3.0/3.1 using their PPS capability. There is no buck or boost converter on the board as these component is already in your USB-C charger. We will explore how to implement constant voltage (CV) and constant current (CC), two modes that are featured in all of the standard bench power supplies.

Can I charge the power supply with a standard USB C/a charger?

So that I can charge the power supply anytime with a standard USB C/A charger. Overall the design is minimalist, looks good and carries 2S 18650 battery for the power backup. This project is sponsored by PCBWAY, China based PCB manufacturer having 10 years of experience in working with PCB related products.
