The invention relates to a repeated high-energy ignition system based on ionic current closed-loop control. The repeated high-energy ignition system comprises an upper computer control unit, an ignition control unit, a driving unit, a multi-coil discharging unit and an ionic current detecting unit. The upper computer control unit is used for sending an operation command of a user and displaying the working state of the system; the ignition control unit is connected with the upper computer control unit and an ECU and used for sending an ignition control signal; the driving unit is connected with the ignition control unit and used for power amplification of the ignition control signal; the multi-coil discharging unit is connected with the driving unit and a sparking plug and used for conducting corresponding discharging on the sparking plug; and the ionic current detecting unit is connected with the upper computer control unit, the ignition control unit, the multi-coil discharging unit and a crankshaft, and is used for detecting the working state, sending the working state to the upper computer control unit, generating a feedback signal simultaneously, and sending the feedback signal to the ignition control unit. Compared with the prior art, the repeated high-energy ignition system has the beneficial effects of being many in ignition mode, capable of adjusting the ignition strategy in real time, capable of avoiding fire catching and partial fire catching, capable improving discharging and fuel economy and the like.
