Thanks for the replies..
Iam using a dsPIC33 which does seem to have all the attributes for PWM control incl complementary outputs and deadtime setup. My system is a 400v dc bus that will be connected through an inverter to a 3ph 415v 50Hz bus, with the inverter being controlled through my dsPIC33.
What Iam trying to understand is that I can see for a 3ph 50Hz output I will need 3 Look Up Tables, offset by 120deg and this will give the requires 3 complementary pairs to drive the 6off IGBTs. Bus for a 240V 50Hz output I only need the one Look Up Table, which gives one pair of complementary siganls. Wont I need two for a H-bridge configuration?
Also how do I add the 120deg phase offset for the 3ph version ie. how do you convert 120deg to a value I can use in the code?
Sorry for asking all these questions, but any help is always most appreciated....
