    For reducing the current spikes, you can check your layout. See an optimal layout example as attached. Use dedicated traces right from the shunt resistor to the resistors of
    amplifier. Traces must not be shared with ground planes. Keep traces among MOSFETs and DC bus capacitors as short as possible.

    You can also try with a bigger Vcc capacitor.

    Hi, I have determined the values of my components but I'm not sure that the calculation is good.

    Can someone check my calculations please ?

    bootstrap capacitor : 47nF

    bootstrap diode : BA218

    bootstrap resistance : 100 ohms
