Hi,
i want a phase shifter for PWM signals.
i have a controller with only two pwm output channels. All another PWM channels / output channels are already used. Both PWM Signals have the same frequence and Duty cycle. The first PWM Channel has 0° Phase and the anotherone PWM has 180° output phase. The frequency is between ~1khz and 150khz and the duty cycle is variable from 5 percent to 95 percent. I would like a 8 phasen design power regulator with each another phase from 0° to 360° in 45° steps. I need a circuit or IC, this my first pwm channel with 0° output phase duplicate to further 3 phases to different output phases to each 45°. (The orig. phase has 0° , phase No. 1: 45°, phase No.2: 90°, phase No. 3: 135°). And for the another output pwm channel from controller with 180° output phase shall be same. (The second phase has 180° , phase No. 1: 225°, phase No.2: 270°, phase No. 3: 315°).
How can I achieve this as simple as possible?
Thank you
With Best Regards
