TMS320F28035: GENERATING 50 HZ FREQUENCY WITH VARYING DUTY CYCLE

I want to generate 50 Hz varying duty cycle PWM with an ePwm block on Microcontroller TMS320F28035.But I am not able to get such low frequency.Here is my code for ePwm.When I  displaying on an oscilloscope I am also not able to get 50 % duty Cycle. This is for generating complementary pulses.

void InitEPwm1Example()
{
// Setup TBCLK
EPwm1Regs.TBPRD = 6000000; // Set timer period 801 TBCLKs
EPwm1Regs.TBPHS.half.TBPHS = 0x0000; // Phase is 0
EPwm1Regs.TBCTR = 0x0000; // Clear counter

// Set Compare values
EPwm1Regs.CMPA.half.CMPA = 36000000; // Set compare A value
EPwm1Regs.CMPB = 3600000; // Set Compare B value

// Setup counter mode
EPwm1Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN; // Count up
EPwm1Regs.TBCTL.bit.PHSEN = TB_DISABLE; // Disable phase loading
EPwm1Regs.TBCTL.bit.HSPCLKDIV = TB_DIV4; // Clock ratio to SYSCLKOUT
EPwm1Regs.TBCTL.bit.CLKDIV = TB_DIV4;

// Setup shadowing
EPwm1Regs.CMPCTL.bit.SHDWAMODE = CC_SHADOW;
EPwm1Regs.CMPCTL.bit.SHDWBMODE = CC_SHADOW;
EPwm1Regs.CMPCTL.bit.LOADAMODE = CC_CTR_ZERO; // Load on Zero
EPwm1Regs.CMPCTL.bit.LOADBMODE = CC_CTR_ZERO;

// Set actions
EPwm1Regs.AQCTLA.bit.CAU = AQ_SET; // Set PWM1A on event A, up count
EPwm1Regs.AQCTLA.bit.CAD = AQ_CLEAR; // Clear PWM1A on event A, down count

EPwm1Regs.AQCTLB.bit.CBU = AQ_CLEAR; // Clear PWM1B on event B, up count
EPwm1Regs.AQCTLB.bit.CBD = AQ_SET; // Set PWM1B on event B, downg count

}
