Why don't more devices incorporate full-wave rectifiers as reverse polarity protection?

Recently, I was introduced to the idea of using a full-wave rectifier, in order to protect against reverse polarity damage in DC devices. I hadn't even considered using a rectifier in an already DC circuit, but now that I think about it, why…

What is a "universal bridge"?

I recently came across this intriguing instrument from the 1970s(?): It's a "Universal Bridge" made by Wayne Kerr. It's not a type of device I've come across before and I'm curious what these are (were?) used for.

Bridge rectifier in parallel?

Is it possible to safely double the current limit using 4 bridge rectifiers? In one forum I found someone wrote: Use four bridges, one for each leg. Tie the AC input (cathode to anode) connections across on each bridge. This now makes a single …

How are bridge rectifiers rated?

So I'm getting ready to build a power supply, and it calls for a bridge rectifier. However, I can't find any information about HOW rectifiers are rated, except for a note that (and I don't have it in front of me) reverse voltage should be three…

Power LED bed lamp from mains

I'm attempting to build an LED bed lamp that will be powered by 240V mains. The LEDs are these ones which if I use with a 12V supply and have calculated correctly will draw 0.24W each. I plan to use 5 or 6 of them in the lamp so will consume a…

What is the electrical connection of heatsink plate of PB case bridge rectifier packages?

I'm going to use two PB-case bridge rectifiers of a certain product in my circuit. I need to know the electrical connection of its heat-sink plate (i.e.; to what pin it is connected to, or if it is connected to any), so that I can decide whether I…

Synchronous buck converter using DGD05463 gate driver: High-side gate goes high while low-side is also high --> Shoot-through

I am working on a synchronous buck converter design using the DGD05463 gate driver. The schematic can be seen below (the inductor is 4.7 µH). The input of the driver gets driven by a 400 kHz PWM signal with varying duty cycle. The output is loaded…

How does one compute the ripple currents seen by a rectifier filter capacitor?

Suppose one is designing a full-wave rectifier bridge, with a known maximum current load, and a known input inductance. Assume three-phase for this example, though the same concept applies to single-phase: The ripple current seen by the output…

Why does my MIC4605 keep blowing up?

I'm trying do design a mini-PCB, replacable half-bridge for motor control applications. The primary application is to use it with my modular inverter/BLDC/BDC controller. The controller design assumes 6 signals going to the bridge: GND, OUT, Low…

Configuring baud of USB-Serial bridge

I hope I'm asking this in the right place, I didn't know if it should go on stack exchange or super user instead. Problem Summary: I need to configure the baud rate of a USB to Serial bridge device. What I need to use them for: I need to send…

Why is 4.096V so often used as a voltage reference?

I get that each mV is equivalent to a bit in a 12-bit ADC, but why is 4.096V used so often? I've heard of this being from a "bridge". What does this mean and what is the historical significance?

1n4007 Bridge Rectifier at 220 Volts AC?

So, I just started getting into electronics, and I have built a bridge rectifier using the 1N4007 diodes. So far I have been using this rectifier with a 24 volts step down transformer, but now I need a higher voltage for other purposes. The AC…

Voltage across an unbalanced resistor bridge

In the above circuit R1 = R2 = R4 = 1 ohm and R3 = (11/10) ohm. I have to find the voltage V. Initially I tried using voltage division in (2 ohm/2.1 ohm) x 10 V = 9.52 V and (2.1 ohm/2 ohm) x 10 V = 10.5 V. Subtracting them gives +1 V. Is this…
