USB ports have quietly turned into the default power outlet for phones, laptops, headphones, and even monitors, but the ...

An ideal voltage source maintains a constant voltage and can deliver an unlimited amount of current. This implementation cannot be physically constructed since it requires the voltage source to be ...

Rectifiers and ac-dc power supplies employ large bulk capacitors. During power-up, these capacitors require a large amount of current to charge up, resulting in a large inrush current. This inrush ...

Power supply manufacturers sometimes hear from customers with unfortunate dilemmas, such as, “I need to operate the power supply outside its rated voltage range.” Or, “What happens if I exceed my ...

In an ideal world, devoid of pesky details like contact resistance and manufacturing imperfections, you would be able to double the current that can be provided to a device by doubling the number of ...
