by “Crutschow“, forum member on Electro-Tech-Online.com The lowest input to output voltage drop you can get with a standard bridge rectifier is nearly a volt through the two conducting diodes for each half cycle, even with Schottky diodes in the bridge. That can generate a dissipation of about a watt per amp of output current in […]

Unravelling the RS-232 standard
by Val Gretchev, Electro-Tech-Online forum member One of the most confusing interface standards must be RS-232. Since its introduction in 1962, it has undergone numerous changes as it was put to use in many applications not originally envisioned. Over the years, many products were designed by engineers who interpreted the specifications in their own way […]

Practical electromagnet design
By “Spec“, Electro-tech-online.com forum member Magnetic theory can get a bit convoluted and before you know where you are, you can end up knee-deep in variables, constants, differentials, and integrals.This article reduces the theory down to a simple formula which, hopefully, will give you a feel for electromagnets and allow you to easily design a simple […]

Current Circuit: A bipolar AC/DC MOSFET low-side switch
by Crutschow, Electro-Tech-Online.com community member Here’s a circuit that uses two back-to-back N-MOSFETs and one PNP BJT to form a low-side bipolar switch for either AC or plus/minus DC sources. This has much lower On voltage drop and power loss than a TRIAC (for example a Triac will typically dissipate >10W at 10Arms current whereas […]

How to build a power supply with two different output voltages
by Electro-Tech-Online forum member Crutschow The schematic to the right shows a simple way to get two full-wave rectified voltages from one center-tapped transformer winding and one bridge rectifier. Adding a capacitor filter at the center-tap gives roughly half the DC voltage from the center-tap output to ground as compared to the bridge output to ground. This […]
PIC 16F and register banking explained
by Jon Wilder As some of you have noticed, the internal RAM in the PIC 16F appears to be arranged in “banks”. Each bank holds 128 RAM registers…
