I want to generate three pwm signals in pic16f73. we can generate two pwm signals using ccp1,ccp2 module that i know.but i have to generate 3 pwm signals from three pins.The first pwm signal is +ve half of a sine wave and 10ms gap.the next is +ve half and 10ms gap.if we mix the two signals we have to get an output like a bridge recifier with 100ns gap.the third is continues negative half cycle from one pin.can we use compare mode for this purpose?

pwm signals are not the same as sine signals. Its not clear whether you want to generate pwm's or sine signals ?

sir,
actualy i mean sinewave generation and not pwm generation.My application is for connecting these three signals to two LOW drive and TWO HIGH drive of IRF2110 for sinewave invertor in push pull mode.The two high drives are connected together and iam trying to change the current direction by changing the low drives.
