This highly versatile, reliable transformerless power supply features a stable, adjustable DC output with a relatively high current of around 110 mA. The pulsating direct voltage provided by rectifier D1—D4 […]
Inductive Non Contact Current Sensor Circuit
This non contact inductive current sensor circuit is designed to detect an alternating current (AC) flow within any circuit and its cables, without undergoing any direct contact with the conductor, […]
Current Detector Circuit on PCB Tracks
This High-Gain Current Sensor circuit can be deployed to detect the availability of low-level current flowing though a PCB’s copper lines or traces. Two straight-pin probes are utilized to form […]
Constant Current Adapter Circuit
It is very necessary that this electronics enthusiast needs a constant current source. If this type of need does occur, for instance for test requirements, it can be a item […]
High Current 78XX Regulator Circuit
This power supply circuit has a three-pin voltage regulator IC along with a buffer transistor. This high current 78XX regulator is developed because in its natural form these regulators cannot […]
How to Protect Loudspeakers from Over Current Surge
There are plenty of ways to protect loudspeakers against the switch-on ‘plop’. Many of such ways depends on a clamp circuit moving across the input of power amplifier, so that […]
