Posted on May 17, 2011 at 10:18Thank you very much for your fast help! That means, a adaptive PWM-frequency is possible, to reduce powerlosses in the powermodule. Not bad! Best regards, Micha
Posted on May 17, 2011 at 10:18Hi, I'm use the St7FMC2N6B6 controller in an inverter. Is it possible to change the PWM-frequency while the motor is running? Have the outputs to be seperated? Or can I change the PWM counter prescaler without stopping...
Posted on May 17, 2011 at 10:17Sorry, but with this values the uC stops with malfunction (red LED is blinking). The error occured, if the voltage, which is slowly increasing, reaches 99%. 99% are working well, but if I turn the potentiometer RV2 to ...
Posted on May 17, 2011 at 10:17Hi, I'd like to analyse the switching losses in the power circuite (IGBTs). One time with sinusoid (PWM) voltage, the other one only switching the IGBTs on (for 180°) and off, without reducing the voltage by a PWM. Th...
