MOSFET High Side High Voltage Droop
EDIT: My prior question was resolved due to using standard scope probes and not differential probes. It was all about measurement issues. This question is based on the same circuit, but about ...

Load Cells - 4x full bridge or 4x half bridge?
After some insight to why 4 half-bridge load cells connected parallelly to one ADC is superior to 4 full-bridge load cells in the same way.
I have been informed that the difference in cost of both ...

What are the advantages of an eight diode 3 phase full bridge rectifier?
I'm replacing my car's alternator, and tearing the old one apart, as you do. The alternator is wired in a Y configuration with 8 diodes, 2 on the neutral point, and then the standard 2 on each of the ...

Amplifying audio on piezo buzzer
I want to output an audio signal from a uC to a piezo buzzer. I first tried the obvious solution with a single transistor in series with the buzzer, but at 3V the sound volume was a bit too low.
The ...

Output Voltage Drop and Insufficient Current Consumption in a Full-Bridge DC/DC Converter
I assembled and tested the circuit shown in the schematic on a copper board. Without any load, I can achieve the desired output voltage of 400V. However, when I connect a 400W load, the output voltage ...

Output of a stand-alone full wave rectifier is different from the one in the circuit in which it is implemented
I'm trying to simulate an evening lamp using a NE555 timer and a relay.
To do so, I'm stepping down the 230V AC household voltage to 16V by an RC circuit as shown.
Now, when I take a stand-alone ...

Power output of a full bridge diode rectifier
Assume a simple circuit with a 12 V (RMS) AC supply and a 100 ohms load resistor. The power dissipated is P = V^2/R = 1.44 W.
Now assume that a full bridge diode rectifier (without filtering) is ...

How to choose Duty Cycle value for a Full-Bridge DC/DC Converter
I've noticed that while designing DC/DC converters, some sources (at the bottom of the website, comment of Benjamin Lough) suggest a "rule of thumb" duty cycle of 70%, while others (This is ...

Use a pair of half-bridge drivers to make a full-bridge driver
I intend to use a pair of half-bridge drivers and a logic gate to make a full-bridge driver for controlling my DC motors with 3 standard input pins of Enable, Direction, and Arduino PWM.
I looked at a ...
