    The below IR2130 circuit connected with PIC18F4431(5V supply) and optocoupler(5V supply) and IR2130 supplied by 15V. Pin 2 to Pin 7 will be the input as shown in the circuit that I uploaded. But I can not generate the signal by using one (1) 100uf capacitor at the left hand side and three(3) 10uf capacitor at the right hand side. I know that there should have some calculation need to be done before decide what suitable value to use for capacitor, but I unable to look online. Please help. Thanks
