How do Electronic Converter/Chargers Operate?
Electronic converter/chargers first convert the 120 VAC 60 Hz from the outlet to 120 VDC after it passes through Diode Rectifier #1, the Capacitor then filters the ripple voltage. This 120 VDC voltage is then fed to an Electronic Switching Circuit that converts it to back to AC and increases the frequency from the original 60 Hz to 3,500 HZ. This high frequency AC voltage is now fed to a step-down transformer where the output voltage reduced to approximately 13.6 volts AC and Diode Rectifier #2 converts the AC to 13.6 Volts DC and the Capacitor filters out the ripple.
