DVC-PWM PWM PWM duty control device using level band type DVC-PWM controller for electric generator

摘要

The present invention relates to a PWM duty ratio control device using DVC-PWM control of a level band structure, which has a rapid control response speed. The PWM duty ratio control device of the present invention comprises: a voltage comparing unit; a level band comparator for performing comparison with an error value to form a control section; and a DVC-PWM driver (81) for forming a PWM duty ratio for each control section.
