Phase correct PWM using timer 4 of STM32F407 micorcontroller

Hi, I am using the 176 Pin STM32F407 microcontroller. I want to generate the phase correct PWM using timer 4 ch1 and ch2, so please guide me for the same. The wave form is attached for driving a dual input boost converter. The "gate driver" image is the waveform I want to generate. and "boot " is the circuit I want to drive. So please tell me the timer configuration for this.
