5 volts DC Regulator Without Transformer Using MOSFET
This is 5 volts DC Regulator power supply that without the transformer so small size, use the MOSFET is based. It is suitable the digital circuit. Caution! This circuit requires very careful to create. Because there is a high voltages many areas. The diodes D1 to D4 are used to …
Mini Emergency Lighting
This mini emergency lighting are used to automatically give lighting when ac line power go out. Which they consist of one lamps, a battery, and a low voltage sensor. This projects design take advantaged of simple circuit techniques and cheap. Special feature: 1. Small-sized : output with 2.4V 5W lamp …
Rectifier by zener diode
The bridge rectifier circuit uses diode 4 the the converter AC to DC, but this circuit uses zener diode as a rectifier instead of diode plain will be current in the direction of the direct bias in the cycle the first current flows through D1 to. to load and then …
