The invention relates to a hybrid energy storage pulsed power supply based on single-phase bridge capacitance conversion, belonging to the technical field of pulse power. The hybrid energy storage pulsed power supply is characterized in that a positive electrode of a primary power supply and a negative electrode of the primary power supply are connected to two ends of a coupling inductor L1 through a main switch respectively, a load is connected to two ends of a coupling inductor L2, the two ends of the coupling inductor L1 are also in parallel connection with a unidirectional bridge capacitance conversion circuit, the unidirectional bridge capacitance conversion circuit includes two bridge arms alternately conducting and a switching capacitor connected between the two bridge arms, each bridge arm includes a set of controllable switches connected in series in the same direction, and the switching capacitor alternately connected in series in the conducting bridge arms and is connected between the controllable switches of each bridge arm. In the hybrid energy storage pulsed power supply based on single-phase bridge capacitance conversion, the leakage inductance energy of two bridge arm coupled inductors which are periodically and alternately conducted is collected by the conversion capacitance and is used for reversely turning off a thyristor in the next discharge cycle, so thatthe energy utilization efficiency is improved.
