    Abstract: Taking the AP1000 nuclear power unit's debugging process based on the project as an example, the output fluctuations and main fuse blowing faults occurred during the recharging of the battery after the discharge was completed by the 1E-Class charger. The corresponding processing measures such as the control board firmware and standard interface board, after simulation and field verification, the output oscillation of the AP1000 1E-Class charger and the main fuse blowing fault have been effectively handled, ensuring the safe and stable operation of the 1E DC and UPS systems.
    Key words: AP1000 nuclear power unit; 1E-Class charger; output oscillation; main fuse blowing; loop controller
