三相t型逆变器svpwmc语言实现

以下是三相T型逆变器SVPWM程序的C语言实现：

#include <stdio.h>
#include <math.h>

#define PI 3.14159265358979323846

int main() {
    double Vdc = 220; // 直流电压
    double Vref = 100; // 期望输出电压
    double theta = 45 * PI / 180; // 期望输出电压的相位
    double Ts = 0.0001; // PWM周期
    double Ta, Tb, Tc; // 三相输出的占空比
    double t1, t2, t3, t4, t5, t6, t7, t8, t9;

    // 计算矢量大小和方向
    double Vm = Vref / sqrt(3);
    double Va = Vm * cos(theta);
    double Vb = Vm * cos(theta - 2 * PI / 3);
    double Vc = Vm * cos(theta + 2 * PI / 3);

    // 计算空间向量
    double Vab = Va - Vb;
    double Vbc = Vb - Vc;
    double Vca = Vc - Va;
    double Va_max = Vdc / sqrt(3);
    double Vab_max = Va_max * 2 * sin(30 * PI / 180);
    double Vbc_max = Va_max * 2 * sin(-90 * PI / 180);
    double Vca_max = Va_max * 2 * sin(150 * PI / 180);
    double Ma = Vab / Vab_max;
    double Mb = Vbc / Vbc_max;
    double Mc = Vca / Vca_max;
    double alpha = 1 - Ma / 2 - Mb / 2 - Mc / 2;
    double beta = sqrt(3) * (Mb - Mc) / 2;
    double gamma = sqrt(3) * (Ma - Mb) / 2;

    // 计算PWM波形
    double Ta1 = (alpha - gamma) / 2;
    double Tb1 = (alpha + beta) / 2;
    double Tc1 = (alpha - beta) / 2;
    double Ta2 = (1 - gamma) / 2;
    double Tb2 = (1 + beta) / 2;
    double Tc2 = (1 - beta) / 2;
    double Ta3 = (gamma + 1) / 2;
    double Tb3 = (beta - gamma) / 2;
    double Tc3 = (1 - alpha) / 2;

    // 生成SVPWM波形
    t1 = Ts * Ta1;
    t2 = Ts * (Ta1 + Tb1);
    t3 = Ts * (Ta1 + Tb1 + Tc1);
    t4 = Ts * Ta2;
    t5 = Ts * (Ta2 + Tb2);
    t6 = Ts * (Ta2 + Tb2 + Tc2);
    t7 = Ts * Ta3;
    t8 = Ts * (Ta3 + Tb3);
    t9 = Ts * (Ta3 + Tb3 + Tc3);

    // 输出控制信号
    Ta = (t1 <= t2 && t1 <= t3) ? 1 : 0;
    Tb = (t4 <= t5 && t4 <= t6) ? 1 : 0;
    Tc = (t7 <= t8 && t7 <= t9) ? 1 : 0;

    printf("Ta=%f, Tb=%f, Tc=%f\n", Ta, Tb, Tc);

    return 0;
}
