240V Single phase fan controll via mosfer H bridge

This is a single phase fan control system for small (0.1-2KW) fan motors, using a mosfet H bridge at 400VDC, looking for 2pwm outputs to control the H bridge (1 for + side and 1 for - side) with 0-10V control signal and enable inputs using a Microchip PIC device, preferably a PIC16F device. older microchip AN note attached
