the low-voltage part comprises a main switch 106 and a main energy storage capacitor 107, wherein one end of the main switch 106 is connected with one end of the main energy storage capacitor 107, and the other end of the main switch 106 is connected with one end of the primary side of a saturation transformer 108; the positive polarity end of the main energy storage capacitor 107 is connected with one end of the inductor 105, and the negative polarity end is connected with the other end of the primary side of the saturable transformer 108; the other end of the inductor 105 is connected to the cathode end of the diode 104, the anode end of the diode 104 is connected to one end of the charging resistor 102, the other end of the charging resistor 102 is connected to the rectifier bridge 101, the positive polarity end of the primary capacitor 103 is connected to the anode of the diode 104, and the negative polarity end of the primary capacitor 103 is connected to one end of the primary side of the saturable transformer 108; the main switch 106 is controlled by a pulse generator 111, a photoelectric conversion module 112 and a drive circuit 113; one end of the pulse generator 111 is connected with one end of the photoelectric conversion module 112, the other end of the photoelectric conversion module 112 is connected with the driving circuit 113, the other end of the driving circuit 113 is connected with one end of the main switch 106, so that the main switch 106 is turned off and on, and the energy on the main energy storage capacitor 107 is coupled to the secondary side through the primary side of the saturable transformer 108;
the high-voltage part mainly comprises a saturable transformer 108, a first energy storage capacitor 109, a second energy storage capacitor 110, a magnetic switch 114, an adjustable inductor 115, a load 116 and a fast recovery high-voltage diode 117; one end of the primary side of the saturable transformer 108 is connected with one end of the main energy storage capacitor 107, and the other end is connected with one end of the main switch 106; one end of the secondary side of the saturable transformer 108 is connected to one end of the first energy storage capacitor 109, and the other end of the secondary side of the saturable transformer 108 is connected to the other end of the first energy storage capacitor 109; one end of the second energy-storage capacitor 110 is connected to one end of the first energy-storage capacitor 109, the other end of the second energy-storage capacitor 110 is connected to one end of the adjustable inductor 115, one end of the magnetic switch 114 is connected to one end of the adjustable inductor 115, the other end of the magnetic switch 114 is connected to the load 116, one end of the fast recovery high-voltage diode 117 is connected to one side of the adjustable inductor, and the other end is connected to one end of the secondary side of the saturable transformer 108.
When the multi-pulse width output magnetic compression power supply works, the power frequency alternating current power supply 100 inputs alternating current voltage, and the alternating current voltage is rectified into direct current voltage through the rectifier bridge 101. The rectified dc voltage charges a primary capacitor 103 through a charging resistor 102, and after a while, the primary capacitor 103 charges a main energy storage capacitor 107 through a diode 104, an inductor 105, and a primary side of a saturable transformer 108. The pulse signal generated by the pulse generator 111 is converted into an optical signal by the photoelectric conversion module 112, the optical signal is converted into an electrical signal, the electrical signal is transmitted to the driving circuit 113 to control the conduction of the main switch 106, at this time, the energy on the main energy storage capacitor 107 is coupled to the secondary side of the transformer through the main switch 106 and the primary side of the saturable transformer 108, the transmitted energy is charged in parallel to the first energy storage capacitors 109 and 110, when the first energy storage capacitors 109 and 110 are charged to the maximum value (at this time, the voltage polarity on the first energy storage capacitor 109 is up-positive and down-negative, and the voltage polarity on the second energy storage capacitor 110 is up-negative and down-positive), the saturable transformer 108 just reaches saturation, at this time, the inductance of the saturable transformer 108 drops sharply, the loop formed by the first energy storage capacitor 109 connected in parallel to the saturable transformer 108 discharges rapidly, and when the voltage polarity on the plate of the first energy storage capacitor 109 is reversed (from the original up-positive and-negative Positive), the polarities of the voltages at the two ends of the first energy-storing capacitors 109 and 110 are the same, and the voltages are superposed, so that the potential between the second energy-storing capacitor 110 and the magnetic switch 114 jumps from the original "zero" potential to about 2 times of the voltage value at the two ends of the first energy-storing capacitor 109 (or the second energy-storing capacitor 110), at this time, the magnetic switch 115 is saturated, and the energy stored in the energy-storing capacitors 109 and 110 is connected in series to discharge to the load rapidly.
The discharge time is as follows:
wherein: l is the inductance of the adjustable inductor 115 and C is the series capacitance of the first energy- storage capacitors 109, 110. With the change of the inductance value of the adjustable inductor 115, the discharge time is changed accordingly, the rising edge of the pulse is affected, the width of the pulse is changed, and the adjustable inductor 115 is changed discontinuously, so that multi-pulse width output is realized.
The fast recovery high-voltage diode 117 is used for reducing the pre-pulse of the load, the same fast recovery high-voltage diode 117 can play a role of freewheeling when the second energy storage capacitor 110 is charged, and can be quickly cut off when the first energy storage capacitors 109 and 110 release energy to the load, so that the process can be equivalent to the most common C-L-R series second-order circuit, and the inverse peak of the pulse of the load can be effectively reduced.
