I have an Queary ,

How to design Firmware Of Bridge less Pfc Circuit ?

For Below Specifiction 

• input Voltage is varrible(Comes In AC) 
• input current is constant (2.8 amps and 6.6amps )
• output voltage is constant 24vDC
• output Current Is 1.5Amps

Note : Input Device Name Is Constant Current Regulator .

So kindly Suggest How To Design Firmware And Calculation Of Frequency As Per Circuit (Like Inductor RIpple And All)
Circuit Digram Is Attached .
