DC link stabilization of single-phase power factor correction by using differential flatness-based control approach

In high power and high dynamics applications (such UPS or Welding Machine) to reduce line current harmonics, power factor correction PFC regulators are essential. This paper presents an innovative control law for a single-phase PFC boost converter. This kind of system is a nonlinear behavior. Classically, to control the voltage and the current in the converter, a linearized technique is often used to study the stability and to select the …
