Absolutely not! You need to insert a current limiting element of some
type in series with the LV side of the PT. For best efficiency, the
series element (ballast) is usually a low value, high current inductor.
You can then add a PFC across the combination of the inductor and PT to
help counteract the inductive phase shift introduced by the inductive
