Abstract

The present invention relates to a swinging magnetic field generating device and its control method. The device includes a DC power supply U with adjustable output voltage, a capacitor C, a resistor R1, four diodes D1-D4, five switches S1-S5, Three thyristors Q1~Q3, three sets of coils L1~L3; the three sets of coils share a high-voltage DC power supply and high-voltage capacitor; after the DC power supply U charges the capacitor C each time, under the action of the microcontroller, the current The oscillating magnetic field is generated through the coils L1, L2, and L3, and the oscillating magnetic field is output on three sets of orthogonal coil axes. The high-voltage capacitor of the invention is discharged in the three-axis coil successively through one charge, and can generate a high-intensity magnetic field, which not only saves energy, but also significantly increases the frequency of the swinging magnetic field.

Description

technical field [0001] The invention relates to a oscillating magnetic field generating device, in particular to a oscillating magnetic field generating device and a control method for biological or cell research. Background technique [0002] With the continuous progress of biomedicine, people pay more and more attention to the safety of living environment. Existing swinging magnetic field devices are generally realized by switching on and off the power supply to the coil and direction switching of the DC power supply, and it is difficult to achieve high field strength and fast switching of the swinging magnetic field. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the existing oscillating magnetic field generating device, and propose a device that utilizes an automatic switching circuit and a high-voltage capacitor to discharge the coil to realize the oscillating magnetic field. The invention can realize the os...
