TMDSSOLARUNVKIT PWM configuration

Hello TI Team.

I have a question about DC flyback PWM configuration. Why are they configured in slave mode instead of master mode?

PWM_1ch_UpDwnCnt_CNF(3, (CPU_FREQ / (FLYBACK_FREQ)), 0, (CPU_FREQ / (FLYBACK_FREQ * 2)) - 2);

We are using PWM1 for the inverter stage. So that is the master. The flyback uses PWM3 and so it is the slave.

Hi Shamim Choudhury ok, I understand and thank you for information. In this case, I have another question about PWM3 configuration. Right now the channel B of PWM3 have a dead-band configuration.
I want to connect my second DC-flayback to this channel to have two DC flybacks per one PV panel but channel B should be 180 degree phase shifted than channel A.
Could you help me with this configuration to have PWM3B phase shifted 180 degree than PMW3A?
