WebMar 31, 2024 · The presence of a high ripple in the inductor current of a DC-DC converter in a photovoltaic converter chain leads to a considerable decrease in the energy efficiency of the converter. To solve this problem, we consider a current-mode control and for economic reasons we used a single inductor current sensor with a low-pass filter. The purpose of … WebIt received a huge boost in popularity in the form of the world’s first current-mode control (CMC) chip, the Flyback controller UC1842 from Unitrode. In CMC, there is in effect a (fast-acting) “inner” current loop along with the “outer” (slower) “voltage loop” which carries out the output regulation. See the note on ramp
