Synergistic pulse signal generator

Abstract

The invention provides a collaborative pulse signal generating device. The collaborative pulse signal generating device comprises a high-voltage direct-current power supply VH, a low-voltage direct-current power supply VL and at least one group of signal generating circuits. The high-voltage direct-current power supply VH is used for outputting high-voltage direct current to the high-voltage inputend of the signal generation circuit. The low-voltage direct-current power supply VL is used for outputting low-voltage direct current to the low-voltage input end of the signal generation circuit. The high-voltage input end of the pulse signal generation circuit is connected with the output end of the high-voltage direct-current power supply VH, and the low-voltage input end of the pulse signalgeneration circuit is connected with the output end of the low-voltage direct-current power supply VL and used for selectively outputting a high-voltage pulse signal or a low-voltage pulse signal to aload. Through the structure, high-voltage pulses can be generated in the same pulse signal generating device, and low voltage pulse can be generated, so as to perform selective switching according todifferent requirements and especially ablate completely with a large ablation volume when applied to tumor treatment, and the synergistic effect of high-pressure nanosecond pulses and microsecond pulses can be combined. The problem of tumor heterogeneity is solved, tumor stem cells are ablated, and the immune mechanism of an organism to tumors is stimulated.

Description

technical field [0001] The invention relates to a signal generating device, in particular to a coordinated pulse signal generating device. Background technique [0002] Pulse power technology is developing rapidly, and its application fields are constantly expanding, such as tumor treatment, food processing, water treatment, plasma generation, etc. During tumor treatment, pulse signals are used for tumor ablation.
