Title:
PWM SIGNAL PROCESSING DEVICE AND PWM SIGNAL PROCESSING SYSTEM
Document Type and Number:
Japanese Patent JP2017034834
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a PWM signal processing device capable of outputting by synthesizing a plurality of PWM signals into one without extending an update period of the plurality of PWM signals.SOLUTION: A unique Duty addition unit 5, when a Duty converter 4 time-sequentially outputs a synthesized PWM signal synthesized into one by successively switching Ach, Bch PWM signals for each carrier period, adds an identification duty pulse for identifying a PWM signal of each channel by masking part of a duty signal of Ach, Bch PWM signals.SELECTED DRAWING: Figure 1
