三相spwm半桥逆变电路stm32hal代码

下面是一个基于STM32 HAL库的三相SPWM半桥逆变电路的示例代码：

#include "stm32f4xx_hal.h"

// 定义PWM周期和分辨率
#define PWM_PERIOD 1000
#define PWM_RESOLUTION 100

// 定义PWM引脚
#define PWM_PIN_A GPIO_PIN_0
#define PWM_PIN_B GPIO_PIN_1
#define PWM_PIN_C GPIO_PIN_2
#define PWM_PORT GPIOA

// 定义相位偏移
#define PHASE_SHIFT_A 0
#define PHASE_SHIFT_B 120
#define PHASE_SHIFT_C 240

// 定义占空比数组（0-100）
uint16_t dutyCycle[PWM_RESOLUTION] = {50, 60, 70, /* ... */};

TIM_HandleTypeDef htim1;
TIM_OC_InitTypeDef sConfig;

void HAL_TIM_PWM_MspInit(TIM_HandleTypeDef *htim)
{
  GPIO_InitTypeDef GPIO_InitStruct;
  if (htim->Instance == TIM1)
  {
    __HAL_RCC_TIM1_CLK_ENABLE();
    __HAL_RCC_GPIOA_CLK_ENABLE();

    GPIO_InitStruct.Pin = PWM_PIN_A | PWM_PIN_B | PWM_PIN_C;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
    GPIO_InitStruct.Alternate = GPIO_AF1_TIM1;
    HAL_GPIO_Init(PWM_PORT, &GPIO_InitStruct);
  }
}

void initPWM()
{
  htim1.Instance = TIM1;
  htim1.Init.Prescaler = 0;
  htim1.Init.CounterMode = TIM_COUNTERMODE_UP;
  htim1.Init.Period = PWM_PERIOD - 1;
  htim1.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
  HAL_TIM_PWM_Init(&htim1);

  sConfig.OCMode = TIM_OCMODE_PWM1;
  sConfig.OCPolarity = TIM_OCPOLARITY_HIGH;
  sConfig.OCFastMode = TIM_OCFAST_DISABLE;
  sConfig.Pulse = 0;
  HAL_TIM_PWM_ConfigChannel(&htim1, &sConfig, TIM_CHANNEL_1);
  HAL_TIM_PWM_ConfigChannel(&htim1, &sConfig, TIM_CHANNEL_2);
  HAL_TIM_PWM_ConfigChannel(&htim1, &sConfig, TIM_CHANNEL_3);
}

void setPWMDutyCycle(uint8_t channel, uint16_t duty)
{
  if (channel == 1)
  {
    __HAL_TIM_SET_COMPARE(&htim1, TIM_CHANNEL_1, duty);
  }
  else if (channel == 2)
  {
    __HAL_TIM_SET_COMPARE(&htim1, TIM_CHANNEL_2, duty);
  }
  else if (channel == 3)
  {
    __HAL_TIM_SET_COMPARE(&htim1, TIM_CHANNEL_3, duty);
  }
}

void updatePWM(uint8_t step)
{
  uint8_t indexA = (step + PHASE_SHIFT_A) % PWM_RESOLUTION;
  uint8_t indexB = (step + PHASE_SHIFT_B) % PWM_RESOLUTION;
  uint8_t indexC = (step + PHASE_SHIFT_C) % PWM_RESOLUTION;

  setPWMDutyCycle(1, dutyCycle[indexA]);
  setPWMDutyCycle(2, dutyCycle[indexB]);
  setPWMDutyCycle(3, dutyCycle[indexC]);
}

int main(void)
{
  HAL_Init();
  initPWM();

  while (1)
  {
    for (uint8_t i = 0; i < PWM_RESOLUTION; i++)
    {
      updatePWM(i);
      HAL_Delay(10); // 设置PWM更新的时间间隔
    }
  }
}

这是一个简单的示例代码，你可以根据自己的需求进行修改和优化。请记得根据你的硬件连接情况修改引脚定义和相位偏移值，并根据需求调整PWM周期和分辨率。
