Building a Graetz rectifier bridge circuit on a breadboard

Customer:

As a teacher, I’m trying to build a rectifier circuit with my students using a Graetz bridge (discrete diodes, not an IC implementation), a transformer, a capacitor, and a breadboard. I’d like to know: do you stock the components I need? From your experience and expertise, is this project technically feasible?

Kao nastavnik, pokušavam sa svojim učenicima napraviti elektronički – ispravljački sklop s ispravljačkim diodama (Greatzov most); ne u izvedbi integriranim čipom), transformatorom, kondenzatorom – koristeći eksperimentalnu pločicu. Po vašem iskustvu, stručnom znanju – je li ova moja ideja uopće izvediva – s tehničke strane (teoretski znam da jest).

This is a great project! I found a reference schematic online that might help.

Unfortunately we don’t stock transformers.

For the rectifier diodes, the 1N4007 should work well for this project.

We don’t have the main filter capacitor at 4700 µF in stock, but we do have a 100nF ceramic capacitor (marked “104”) that can serve as C2.

For the LED, you can use 5mm LEDs. To make them work properly, you can use two 330Ω resistors connected in series.

For the breadboard, we have prototyping breadboards available.

super projekt! Napravio sam kratko istraživanje s našim proizvodima. Evo referentna shema koju sam pronašao na internetu: Ove diode bi trebale biti OK za ovaj projekt: https://soldered.com/hr/proizvod/1n4007-dioda/ Kondenzator C1 od 4700 uF koji je glavni filter na izlazu također nemamo točno tu vrijednost Ovo je kondenzator C2 označen sa “104” koji u stvari ima vrijednost 100nF https://soldered.com/hr/proizvod/keramicki-kondenzator-100nf-50v/ LEDica, možete koristiti ove: Paket 5mm LED dioda (13 komada) – Soldered Electronics Kako bi LEDica radila OK, možete koristit dva ova spojena u seriju: https://soldered.com/hr/proizvod/25x-330ohm-otpornik-za-ledice/ Eksperimentalna pločica: https://soldered.com/hr/proizvod/eksperimentalna-plocica-protoplocica-u-pcb-verziji/ Nadam se da ovo pomaže :slight_smile:
