Parallel-controlled circuits operate as self-controlled, variable resistors, connected in parallel to the load impedance (parallel loads). They react extremely fast and also control immediately pulses and very short mains break-downs, resulting from strong loads....
Dual Polarity Power Supply Two versions of a dual polarity power supply with printed circuit board artwork. The supplies are built around the popular LM317 & 337 complementary voltage regulators which offer very high...
The standard buck regulator circuit delivers a +5V output. This is a rather straightforward circuit and will operate with a wide spread of component values. Optimal values should be selected however to get minimal...
This is a simple charger you can build for devices. It can be modified for any device. This may need no modification for devices that are charged using PC USB port.
Jonathan Westhues site of Intriguing Projects include A Test Instrument for HF/LF RFID and a compiler that starts with a ladder diagram and generates native PIC16 or AVR code.
The fig. 6.2 shows the circuit of a regulated power supply for +/- 15 V and 5 A. The output voltages are adjustable between 12 and 17 V. A tape-wound core transformer is used....
