Abstract: This article presents a combined control method of resonant frequency tracking and constant voltage/constant current charging mode for undersea wireless power transfer (UWPT) systems. This ...
FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...
[Afroman] contacted us to share his new video on the LM317. The humble LM317 adjustable voltage regulator is everywhere. From wifi routers, to high spec lab equipment. Given a noisy input and a ...
Abstract: A network theoretic approach is employed to derive a number of circuits for i) constant load current, ii) constant load voltage, and iii) constant magnitude input current, when the load ...
The "Circuit Shorts" series continues! This time, Saar covers dual-BJT constant current. There are many ways of driving LEDs and each has its merits for a particular application. Using a current ...
The LED driver automatically adjusts the output voltage to keep the output current constant and therefore the light output constant. This works with a single LED or with a chain of string of LEDs ...
You need to know how to investigate how current changes with voltage for a component, eg for a resistor (or wire) at constant temperature, a filament lamp and a diode. You should be familiar with the ...
Biasing avalanche photodiodes (APDs) at constant current optimizes performance at low signal levels, eliminates adjustments over temperature, and accommodates large sample differences. An avalanche ...
