Boost Converter with Analog PI Controller

Boost Converter with Analog PI Controller (Used only Op Amp & 555 Timer)

Boost Converter with Analog PI Controller. The PI controller used +-5V supply to work. It does not requires any digital controller. It only need five operational amplifiers and one 555 timer to work. It is suitable for making closed-loop DC-DC converter as hobby of for final year project with low budget (using the digital controller to implement PI is expensive). Please note this is just a simulation and it never being tested with actual hardware.
