How Linear Power Supply Work – Regulator
The rectifier is good enough if its a small ripple voltage, but there are stability issues. If the voltage of electricity rise / fall, then the output voltage will also go up / down. Like the rectifier circuit above, if the current higher voltage dc discharge was also decreased. For some applications this voltage changes [...]

How Linear Power Supply Work – Rectifier
Electronic devices should supply the direct current supplied by DC (direct current) which is stable to well. Battery or batteries are a source of DC power supply is best. But for applications that require larger power supply, the source of the batteries is not enough. A major source of power supply is the source of [...]
