三相交频调速系统中的PWM　LSI　HEF4752V

PWM LIS HEF4752V hor Three－Phase Variable Frequencey Variable Speed System

本文主要介绍在三相变频调速系统中能产生三相PWM波形的一种新型大规模集成电路HEF4752V，对以其为核心构造的PWM逆变器作了初步探讨。

In this paper, a new type LSI HEF4752Vwhich can produce three-Phase PWM wave in three-phase variable frequency variable speed system isintroduced. PWM inverter With LSI HEF4752V issearched tentatively.
