Cezar Chirila @ allaboutcircuits.com shows how to build a Class-D amplifier which has amazing efficiency. What is a Class-D audio power amplifier? The answer could be just a sentence long: It is a switching amplifier. But in order to fully understand how one works, I need to teach you all its nooks and crannies. How to Build […]
Soft Latch Power Switch Circuit
https://www.electronics-lab.com/soft-latch-power-switch-circuit/
Dаvid Jones through his Youtube channel EEVblog described in detail how to design a cheap soft latch power switch circuit, using one push button switch to toggle your circuit power on and off with the following design requirements: Zero power when off. One on/off switch. Standalone(no MCU). General components only (Diodes, Transistors, ..ect). Minimal parts. […]
Circuit delivers constant power to a load
https://www.electronics-lab.com/circuit-delivers-constant-power-load/
Kiril Karagiozov @ edn.com has a circuit idea that is able to deliver constant power to a load. This is done by generating energy pulses, independent of resistance of the load. If you have a load with a variable or poorly specified resistance and want to regulate the power applied to it (a heater for […]
