在EPWM中初始化了各子模块，具体如下：
      EPwm1Regs.TBPRD = 1500; //1430;//                      // 20kHz       //1430=21k
      EPwm1Regs.TBPHS.half.TBPHS = 0x0000;          // Phase is 0
      EPwm1Regs.TBCTR = 0x0000;                      // Clear counter
      EPwm1Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN;  // Count up to down
      EPwm1Regs.TBCTL.bit.PHSEN = TB_DISABLE;       // Disable phase loading
      EPwm1Regs.TBCTL.bit.HSPCLKDIV = TB_DIV1;       // Clock ratio to SYSCLKOUT
      EPwm1Regs.TBCTL.bit.CLKDIV = TB_DIV1;          //
      EPwm1Regs.TBCTL.bit.SYNCOSEL = TB_CTR_ZERO;
。。。。。。

               if((wCurrentRef >= 2048) && (dwVoltOutTemp < 0))       //area4
            {
                     if(dwVoltOutTemp > -50)
                     {
                              dwVoltOutTemp = -50;
                     }
                     EPwm1Regs.CMPA.half.CMPA = -dwVoltOutTemp;
                     EPwm1Regs.CMPB = 1500;
                           }
请问当条件满足时输出的模型是怎么样的？
