Pcpwm pic18f2431

Hi All

Using the PCPWM module to drive led arrays at the moment. All working fine but does anyone know if it posiable to put each output out of phase with each other so say that with all 3 channels something like this happens:

PWM1 start
1/3 cycle delay
PWM2 start
1/3 cycle Delay
PWM3 start

and so on

Main aim here is to help the PSU out so all 3 chanels are not being hit on at the same time.

Any ideas appriciated.
