    Abstract: PURPOSE: A converter and inverter system for modulating a pulse width is provided to improve the reliability of the converter and inverter system, and to decrease the price and the volume by applying a DC link electric power balanced method and an energy control method at a PWM converter-inverter system. CONSTITUTION: A converter and inverter system includes an encoder(110), a speed controller(112), a flux controller(113), a current controller(114), the first coordinate converter(115), and the first EPLD(Erasable Programmable Logic Device)(116). The encoder(110) detects a real speed of an AC motor(50) and a location of a rotator magnetic flux vector. The speed controller(112) builds up a q-axis current instruction value by comparing an external speed instruction value and the real speed of the AC motor(50). The flux controller(113) builds up a d-axis current instruction value by comparing an external magnetic flux instruction value with a flux calculated through a numerical formula. The current controller(114) builds up a voltage instruction value for a d-q axis current by using the location of the rotator magnetic flux vector, the q-axis current instruction value, and the d-axis current instruction value. The first coordinate converter(115) converts a coordinate of the voltage instruction value by using the location of the rotator magnetic flux vector. The first EPLD(116) generates a PWM signal needed in an inverter(40) through a fixing coordinate system voltage instruction value converted by the first coordinate converter(115).
