This is the extended explanation for the problem and above is the code which i have tried, due to messge limit i have extended this
I have tried to write code in stm32f411ceu6 (blackpill) for generating PWM pulse which will be given to my esc using ir2101. I am using stm32cubeMX for generating code. In stm32cubeMX i have initailized TIM 1 , CH1,CH2, CH3 with complementry mode, pin as Pulldowm, which will be given to three ir2101 HIN and LIN pin for turning on and off of n channel mosfet. The issue i am getting is in the code the TIM1 CH1 pin is pulled to high and after two step it should turn off the PWM but it generate dummy pulse which lead B phase mosfet to heat. when i set the dutycycle to 10 then CH1 duty cycle is 10 and CH1N is 90 but this is not turning mosfet correctly, I need is both CH1 and CH1N duty cycle should be 10.

> __HAL_TIM_SET_COMPARE(&htim1, TIM_CHANNEL_1, 0);
Do you ever set the value to something other than 0? I can't see any places where this is done. Setting CCR1 to 0 will output a DC signal, not a pulse.
If your period is 1000 and you want a 10% duty cycle, set CCR1 to 100.

Initially i am making 0 and then setting the value calculated from compareValue in it
