A circuit described as the LED AC mains voltage level indicator may be used to monitor and show the current voltage status of any 220 V or 120 V mains […]
Simple Voltage Controlled Oscillator Circuit
The circuit as shown in Figure below presents a 555 as an extremely simple, voltage-controlled oscillator (VCO). The VCO’s output frequency (U1) differs contrariwise with the input voltage. Using a […]
1.2 V to 32 V 10 Amp Adjustable Voltage Power Supply using LT1038
The LT® 1038 is a 3 terminal regulator which is specifically designed to handle an output current of 10 A at voltage levels ranging from over 1.2 V to 32V. […]
Switching Triacs Safely using Zero Voltage (ZVS)
Zero-voltage switching (ZVS) for triacs is implemented by providing a controlled power to the load, through an ON/OFF switching of the line voltage, which is specifically at the zero crossing […]
LED Voltage Monitor Circuit
A well balanced power supply is completely necessary for the precise functioning of computers and TTL circuits. A voltage fluctuation of 10% is undoubtedly not bearable, it is therefore advisable […]
Low Voltage Crystal Oscillator Circuit
It is quite simple to build a crystal oscillator by using a field impact transistor. This low voltage crystal oscillator circuit functions at comparatively low supply voltages, from 1.5 volts […]
