This circuit diagram illustrates a simple AC-to-DC power converter. It utilizes a diode bridge rectifier to convert AC input into pulsating DC. A voltage regulator (LM7806) filters and stabilizes the DC voltage to a regulated 12V output. Capacitors C1 and C2 smooth the DC voltage, while resistors R1, R2, R3, and R4 provide additional filtering and biasing. The regulated 12V output can be used to charge a mobile battery.
