加入停止定时器函数，输出波形得到改善。

void MX_PWM_Stop(void)
{
	//----------------------使用停止函数后会导致移相角度为60度----------------------------------------------------------------
#if 1	
	
 //------Tim1 PWM定时器初始化------------------  
	HAL_TIM_OC_Stop(&htim1,TIM_CHANNEL_1);
	HAL_TIMEx_OCN_Stop(&htim1,TIM_CHANNEL_1);
	
	HAL_TIM_OC_Stop(&htim1,TIM_CHANNEL_3);
	HAL_TIMEx_OCN_Stop(&htim1,TIM_CHANNEL_3);
	
	HAL_TIM_OC_Stop(&htim8,TIM_CHANNEL_2);
	HAL_TIMEx_OCN_Stop(&htim8,TIM_CHANNEL_2);
	 //------Tim8 PWM定时器初始化-------------
	HAL_TIM_OC_Stop(&htim8,TIM_CHANNEL_1);
	HAL_TIMEx_OCN_Stop(&htim8,TIM_CHANNEL_1);	
	
	
	HAL_TIM_OC_Stop(&htim8,TIM_CHANNEL_3);
	HAL_TIMEx_OCN_Stop(&htim8,TIM_CHANNEL_3);
	
	HAL_TIM_OC_Stop(&htim1,TIM_CHANNEL_2);
	HAL_TIMEx_OCN_Stop(&htim1,TIM_CHANNEL_2);
	
	
	__HAL_TIM_SET_COUNTER(&htim1,T_PRD);
	__HAL_TIM_SET_COUNTER(&htim8,0);  //1200 CH3
	HAL_TIM_Base_Stop(&htim1);
	HAL_TIM_Base_Stop(&htim8);
