Voltage Control Boost Converter

[danilorj]

Hi guys,

I need to control the input and the output of a boost converter. First, the input I can control using a mppt algorithm to find the maximum voltage my fuel cell can deliver and the voltage associated with it. But the problem is the output of it that I need to control too, because it will be the input of a inverter and it should be at a fixed value. I don't know whether it can be done just using control techniques or the topology should be changed anyway.
I'm sending this picture that shows the input of the boost converter being controlled.
I would appreciate any help.

There are IC's made to regulate switched coil converters.

The control pin sends pulses, which turn the mosfet on and off.

The IC has sense wires, to detect output voltage, detect coil current, have a reference voltage applied, etc.

Your system will have a fuel cell, boost converter, and inverter. You might want to see if you can combine the converters into one inverter which steps up voltage. It could be more efficient that way.
