The pulse power supply system is generally divided into a primary power supply, an intermediate energy storage and pulse forming system and a conversion system. However, the low energy storage density of the primary power supply cannot meet the energy requirement of electromagnetic emission, so there is usually an intermediate energy storage part, and the common forms are capacitive energy storage, inductive energy storage and mechanical energy storage. Under the same power density condition, the energy storage density of the inductor is one order of magnitude higher than that of the capacitor, compared with mechanical energy storage, the inductor energy storage mode is flexible, static energy is stored, a cooling device is simple, configuration is easier to realize in daily research and stress application, in addition, the maintenance is convenient, and the service life is longer. Therefore, the inductive energy storage has larger application potential in the field of pulse power supplies.

The switching section 101 is composed of a thyristor Th1And a diode D1Composition of thyristor Th1Anode of (2) and diode D1Are connected to form a port 101A, a thyristor Th1Cathode and diode D1Is connected to form a port 101B; the control part 102 is composed ofCapacitor C1A reverse diode D13And a diode D11And (4) forming. Diode D13、D11The common anode connection method is adopted to form a port 102C and a diode D13The cathode is connected with one side of the capacitor, the other side of the capacitor is connected with another diode D11A cathode connection forming port 102D; the energy storage part 103 is composed of an energy storage inductor L1Composition of, inductor L1Is connected with the port of the next stage switch part 201A, and a diode D12The anode is connected to port 201A, while the cathode is connected to switch SLAnother port N of the load is connected and then connected. The control portion 102 is connected to the M port of the load through a port 102C, and the switch portion 101 is connected to the positive pole of the power source Us through a port 101A. The switching section 101, the control section 102, and the energy storage section 103 form a first stage of the topology, which is also a basic loop of the overall circuit topology. Each basic topology comprises a switch part, a control part and an energy storage part. The whole topology is formed by n basic topological connections. The negative pole of the power supply is connected to ground and to port n03A of the energy storage section of the nth stage, so that the entire topology is driven by the primary power supply UsAnd the n-stage basic circuit topology and the load G form a complete loop, and can work to realize the functions of the circuit.
The working process of the circuit is divided into three stages. Before the circuit works, the capacitor C1～CnPre-charged with a voltage.
In the first stage, a constant voltage power supply supplies power to an inductor L1～LnAnd charging in series. The charging circuit is shown in FIG. 2, and triggers the thyristor Th1～ThnConducting, constant voltage source Us to inductor L1～LnCharging in series, when the current in the inductor reaches a certain value, switching SLAnd (5) closing. The next stage is entered. As can be seen from the analysis, any two capacitor loops in each loop have diodes D connected in series in the reverse direction during the charging process13～Dn3Exist such that C1～CnThe inductor is completely isolated from the charging loop, so that the inductor current can rise linearly without ripples. Compared with the method without adding an isolation diode, the method has the advantages that the ripple waves of the inductive current and the capacitor voltage are effectively controlledAnd long-term large high-frequency oscillations in inductors and thyristors.
And in the second stage, in the commutation process, the charging loop is removed from the main circuit by turning off a thyristor and a diode which is connected with the thyristor in parallel in the charging loop, and the charging loop is converted into a discharging loop. Because the commutation process is short in duration, it can be considered that the current in the energy storage inductor remains substantially unchanged. The commutation circuit includes: (1) capacitor C1Switch SLLoad G, diode Dn2Constant voltage source UsThyristor Th1Forming a current conversion loop; (2) capacitor CkThyristor ThkDiode D(k-1)2(where k is 2, 3 … … n), load G, switch SLForming a commutation loop.
The thyristor turn-off process is explained first. In the two commutation loops above (where i is 1, 2, 3 … … n), a capacitor C is passed throughiThe current in the capacitor rises from zero to the thyristor ThiWhen the current is the same, the thyristor is naturally turned off. Due to CiVoltage is left on, current continues to flow through, and thyristor ThiParallel diode DiConducting to the thyristor ThiApplying reverse voltage, and ensuring that the thyristor Th is turned off when the period of time is longer than the thyristor turn-off timeiAnd (4) reliably shutting down.
The process of turning off the diode in parallel with the thyristor is then explained. The diodes are divided into D due to different bearing voltages1And Dk(where k is 2, 3 … … n). (1) Diode D1Is turned off. Capacitor C1Voltage U onC1Gradually decreased, power supply UsVoltage on load G, U, constantGAt a positive value, diode D1Voltage U onD1＝UC1-UG-Us. Thus diode D1The voltage on gradually decreases to a negative value, diode D1And is shut off by being subjected to negative pressure. (2) Diode Dk(where k is 2, 3 … … n). Diode DkVoltage U onDk＝UCk-UG. Similarly, when the diode DkThe voltage on gradually decreases to a negative value, diode D1Due to the bearingIs turned off by negative pressure.

Third stage, inductance L1～LnAnd (4) parallel discharge process. Inductor LiDiode Di2Capacitor Ci(where i is 1, 2, 3 … … n), a load G, a switch SLN discharge circuits are formed. These n loops discharge the load G in parallel.
Through the process, the energy of the primary power supply can be converted into the pulse power supply meeting the electromagnetic emission requirement, and the basic functions of the pulse power supply are realized.
