Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] Such as figure 1 As shown, the present invention includes a main circuit and a control circuit, wherein:
[0029] 1) Main circuit: including rectification circuit, filter circuit, Boost circuit, inverter circuit, buffer circuit, pulse transformer and pulse rectification circuit. After being rectified and filtered, the 220V AC power is boosted once through the Boost circuit, and then connected to the inverter circuit and the primary of the pulse transformer for secondary boosting. The secondary output of the transformer generates high-voltage pulses after pulse rectification.
[0030]2) Control circuit: including DSP system, PWM amplifier circuit, drive circuit and protection circuit. The three-way PWM signals sent by the DSP system are connected to the respective IGBT drive circuits after passing through their respective PWM amplifying circuits...
