I have designed 2 boost converter both of them have same duty cycle and same L and C values. Voltage input is 12V and with 50% duty cycle I expect to see 24V output from each of them. If I connect them in series I should get arround 48V total output, but for some reason, the top boost converter voltage is pulled down and not giving 24V. Can someone notice my mistake or give me some tips? thank you
