#90869 - induction heating machine |
hi friends
recently i have started a new project named induction heating machine the principle of the machine is heating of substance through high frequency magnetic flux around 20 to 50khz and current is controlled through PWM. my problem is how to do both frequency change with step of 1hz or nearabout and pwm of same after frequency is fixed. there must be two outputs from mcu with opposite phase and dead band is also necessary to save IGBTS.(very similar to 3524 ic). please tell me how to do both thanks kuldeep |
