摘　　要：本文扼要阐明磁力矫形原理,描述用于磁力矫形的脉冲发生器和它的充电过程。该发生器在电压7kV时,释放电容器储能6kJ,其电流峰值已达～40kA。而整个发生器的结构紧凑,它包括充放电回路,电压设定,数码显示和一个得心应手的控制系统。磁力的大小可以通过电压预选器来灵活调节和精确控制。在分析放电回路的基础上得出流过磁锤线圈中的最大放电电流I_(lmax)和被矫工件中感应的最大电流I_(2max)的数学表达式。最后绘出两组曲线族I_c=f(K)和Tc=f(K)。This paper briefly explains the principle of magnetic force correction,describes a pulse generator for magnetic force correction and its chargeprocedure.The generator has been used at a voltage of 7kV,to discharge a 6kJcapacitor bank at currents up to～40kA.The construction of total generatoris compact.It includes charge,discharge circuits,preselecting voltage,digitaldisplay,and a convenient control system with facility.The amplitude of themagnetic force can flexibly be adjusted and can be accuratly controlled bymeans of a voltage preselector. On the basis of analysing discharge circuit analysis expressions have beenderived for the maximum discharge current I_(1max) in the coil of the magnetichammer and for the maximum induced current I_(2max) in corrected work piecerespectively.Finally two groups of curves I_c=f(K)and T_c=f(K)are alsoshown.
