Various embodiments relate to a current loop controller configured to control a boost converter, including: an amplifier configured to scale a measured current; a subtractor configured to subtract the scaled measured current from a desired current and to output an error signal; a controller including an integral part and a proportional part configured to produce a control signal based upon the difference signal and a gain value, wherein the gain value is based upon a measured value tps, wherein tps is the on-time plus the secondary time of the boost converter; and a switch signal generator configured to produce a gate signal based upon the control signal, wherein the gate signal controls the boost converter.
