A pulse magnetic field circuit was designed with the preliminary parameters as follows:
1. The capacitors consist of four Japanese Rubycon flash lamp capacitors (330V 1300μF), configured to achieve a capacitance of 660V 1300μF with a maximum withstand voltage of 720VDC.
2. Two 75A unidirectional thyristors (model CS60-16) are connected in parallel.
3. An STC08H16K single-chip microcomputer (MCU) is used to control the power supply of the boost board, high-voltage output, thyristor driving, LED indication, speaker audio prompts, discharge voltage selection, and timing functions.
4. The capacitor discharge voltage is divided by resistors and compared with a reference voltage. Based on the selected reference voltage, the MCU determines whether the capacitor voltage has reached 200/300/400/500/600V (five levels in total; some levels can also be selected individually), after which the coil is discharged.
5. The boost board is controlled to stop operating simultaneously with capacitor discharge.
6. Interfaces on the circuit board include: 2-pin 12VDC input, 2-pin 12VDC output controlled by a relay, 2-pin high-voltage input, 2-pin 12V cooling fan interface, 2-pin coil interface, 4-pin MCU programming port, and 5-pin reference voltage interface.
7. Hole spacing for 4mm mounting holes: 152*102mm.
8. Circuit board dimensions: 160*110mm.
