PFC Problem in TMDS2MTRPFCKIT (PFC and Motor Control Development Kit using F28035)

Respected Sir,

                           I am using the kit "PFC and Motor Control Development Kit using F28035" and the sample program for Boost PFC control  "PFC2PHIL". In the Increment Build mode 1, initially when there is no DC supply at AC-IN in M2-TB1 the PWM is working fine (50% Duty Cycle for value 0x4000) but as soon as I increase the voltage around 1.8 V the PWM signals simply vanish and there is no output voltage. So I have to restart the controller and re-programme it. Please help?

Thanking you,

Regards,
