This is a compact adjustable power supply that delivers a stable voltage and currents up to 3 amperes. The circuit is very conventional and its voltage output can be varied from 1.25 volts to 25 volts. The main module is the LM350 IC which integrates a voltage regulator and a power stage. It also has [...]

This is circuit 300W Inverter power,so input battery 24V to Output 220Vac 50Hz 300W. I used main Component IC CD4027 , NE555,CA3130 and LM7805. The transistor power MJ15003 driver transformer 24V 10A min. The VR1 – 100K is control Frequency output at 50Hz 50Hz or 60Hz at Square wave signal. The VR2 – 50K is [...]

This circuit will double almost any DC input voltage as well as handling plenty of current. 12 to 24V is just an example. With a few changes, it can also supply any desired output voltage. There are many possible applications. One I can think of would be to get the 28V for the ADC connector [...]
