Power circuit with smoothing filter capacitor

Power circuit with smoothing filter capacitor

Capacitors (smoothing filter capacitors) are used in DC power circuits to form smoothing filter circuits . Shown is the power supply circuit
with smoothing filter capacitors added . Due to the addition of the smoothing filter capacitor , especially due to the charging and discharging characteristics of the capacitor, the DC current in the circuit that was originally unstable and fluctuated became relatively stable and smooth.
