Abstract
This paper investigates the large- and small-signal response
issues and, in particular, the inner loop gain and outer loop response
of an indirect control method for active power-factor correction. The
control scheme is based on sensing the average inductor current and
generating a DOFF (the complement of the switch duty cycle)
which is proportional to the current. The method is demonstrated by
considering the performance of a boost-type active power-factor
corrector (APFC) that does not need to sense the input voltage.
Theoretical and experimental results confirm the validity of the
approach and demonstrate that the proposed method can be useful in the
design of robust APFC with low total harmonic distortion. The indirect
control method investigated in this paper is also compared to the
classical direct APFC control method, pointing to the differences
between the two
