利用 ePWM模块编写三相全桥道交电路的发波程序，载波频4 10Khz

好的，我理解了你的问题。下面是一个基于 ePWM 模块编写的三相全桥道交电路的发波程序，载波频率为 4 10KHz。

#include "F28x_Project.h"

#define PWM_PERIOD 2000  // PWM 周期长度
#define DEAD_TIME 50     // 死区时间长度

void setup_ePWM(void);

void main(void)
{
    // 初始化系统配置
    InitSysCtrl();
    // 配置 ePWM 模块
    setup_ePWM();

    while (1) {
        // 主循环
    }
}

void setup_ePWM(void)
{
    // 配置 GPIO 口
    GPIO_SetupPinOptions(0, GPIO_OUTPUT, GPIO_ASYNC);
    GPIO_SetupPinOptions(1, GPIO_OUTPUT, GPIO_ASYNC);
    GPIO_SetupPinOptions(2, GPIO_OUTPUT, GPIO_ASYNC);
    GPIO_SetupPinOptions(3, GPIO_OUTPUT, GPIO_ASYNC);

    // 配置 ePWM 模块的时钟源
    CpuSysRegs.PCLKCR2.bit.EPWM1 = 1;
    CpuSysRegs.PCLKCR0.bit.TBCLKSYNC = 0;

    // 配置 ePWM1 模块的计数器
    EPwm1Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN;
    EPwm1Regs.TBCTL.bit.PHSEN = TB_DISABLE;
    EPwm1Regs.TBCTL.bit.PRDLD = TB_SHADOW;
    EPwm1Regs.TBPRD = PWM_PERIOD;
    EPwm1Regs.TBPHS.half.TBPHS = 0;
    EPwm1Regs.TBCTR = 0;

    // 配置 ePWM1 模块的计数器时钟分频
    EPwm1Regs.TBCTL.bit.HSPCLKDIV = TB_DIV1;
    EPwm1Regs.TBCTL.bit.CLKDIV = TB_DIV1;

    // 配置 ePWM1 模块的 A/B 相
    EPwm1Regs.AQCTLA.bit.CAU = AQ_CLEAR;
    EPwm1Regs.AQCTLA.bit.CAD = AQ_SET;
    EPwm1Regs.AQCTLB.bit.CBU = AQ_CLEAR;
    EPwm1Regs.AQCTLB.bit.CBD = AQ_SET;

    // 配置 ePWM2 模块
    EPwm2Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN;
    EPwm2Regs.TBCTL.bit.PHSEN = TB_DISABLE;
    EPwm2Regs.TBCTL.bit.PRDLD = TB_SHADOW;
    EPwm2Regs.TBPRD = PWM_PERIOD;
    EPwm2Regs.TBPHS.half.TBPHS = PWM_PERIOD / 3;
    EPwm2Regs.TBCTR = 0;
    EPwm2Regs.TBCTL.bit.HSPCLKDIV = TB_DIV1;
    EPwm2Regs.TBCTL.bit.CLKDIV = TB_DIV1;
    EPwm2Regs.AQCTLA.bit.CAU = AQ_SET;
    EPwm2Regs.AQCTLA.bit.CAD = AQ_CLEAR;
    EPwm2Regs.AQCTLB.bit.CBU = AQ_SET;
    EPwm2Regs.AQCTLB.bit.CBD = AQ_CLEAR;

    // 配置 ePWM3 模块
    EPwm3Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN;
    EPwm3Regs.TBCTL.bit.PHSEN = TB_DISABLE;
    EPwm3Regs.TBCTL.bit.PRDLD = TB_SHADOW;
    EPwm3Regs.TBPRD = PWM_PERIOD;
    EPwm3Regs.TBPHS.half.TBPHS = PWM_PERIOD * 2 / 3;
    EPwm3Regs.TBCTR = 0;
    EPwm3Regs.TBCTL.bit.HSPCLKDIV = TB_DIV1;
    EPwm3Regs.TBCTL.bit.CLKDIV = TB_DIV1;
    EPwm3Regs.AQCTLA.bit.CAU = AQ_CLEAR;
    EPwm3Regs.AQCTLA.bit.CAD = AQ_SET;
    EPwm3Regs.AQCTLB.bit.CBU = AQ_CLEAR;
    EPwm3Regs.AQCTLB.bit.CBD = AQ_SET;

    // 配置死区时间
    EPwm1Regs.DBCTL.bit.OUT_MODE = DB_FULL_ENABLE;
    EPwm1Regs.DBCTL.bit.POLSEL = DB_ACTV_HIC;
    EPwm1Regs.DBCTL.bit.IN_MODE = DBA_ALL;
    EPwm1Regs.DBRED = DEAD_TIME;
    EPwm1Regs.DBFED = DEAD_TIME;
    EPwm2Regs.DBCTL.bit.OUT_MODE = DB_FULL_ENABLE;
    EPwm2Regs.DBCTL.bit.POLSEL = DB_ACTV_HIC;
    EPwm2Regs.DBCTL.bit.IN_MODE = DBA_ALL;
    EPwm2Regs.DBRED = DEAD_TIME;
    EPwm2Regs.DBFED = DEAD_TIME;

    EPwm3Regs.DBCTL.bit.POLSEL = DB_ACTV_HIC;
    EPwm3Regs.DBCTL.bit.IN_MODE = DBA_ALL;
    EPwm3Regs.DBRED = DEAD_TIME;
    EPwm3Regs.DBFED = DEAD_TIME;

    // 启用 ePWM1、ePWM2、ePWM3 模块
    EPwm1Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN;
    EPwm2Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN;
    EPwm3Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN;
    CpuSysRegs.PCLKCR0.bit.TBCLKSYNC = 1;
}

需要注意的是，上面的程序只是一个基础的参考框架，你需要根据具体的需求进行修改和优化。同时，还需要根据具体的硬件平台进行适配和调试。
