固态LTD的脉宽叠加技术仿真
Simulation Study on Pulse Width Superposition of Solid-State LTD
摘要
Abstract
A long pulse width solid-state Linear Transformer Driver(LTD)is designed by means of pulse su-perposition for high voltage,large current and wide range pulses required in biomedical applications of pulsed electro-magnetic fields.To break through the pulse width range under the volt-second product limit of the pulse transform-er,the LTD increases the output pulse width using parallel superposition.The reset circuit of the pulse transformer is designed to improve the output pulse duty cycle of LTD,so that the multi-pulse superposition of the minimum branch LTD can be achieved.A simulation circuit model is built on Pspice to verify the design principle and the effect.In the case of a single-turn pulse transformer with a volt-second product of 146 V·ms,a pulse output with a single-stage voltage of 300 V and a pulse width of 1.6 ms is realized,which is 3 times of its original volt-second product,and a wider range of pulse extension can be achieved by increasing the number of superimposed pul-ses.关键词
