1. A T-type buck-boost power factor correction (PFC) rectifier (TBPR) for providing a low ripple DC output from a mains AC input, the TBPR comprising:
a power inductor;
first and second storage capacitors; and
first, second and third bi-directional switches, the first bidirectional switch connecting a power supply input to a first end of said power inductor, the second bidirectional switch connecting said first end of said power inductor to a first end of said first capacitor and said third bidirectional switch connecting said first end of said power inductor to a first end of said second capacitor, a second end of said first capacitor, a second end of said second capacitor and a second end of said power inductor being connected to a common node, wherein, when the power inductor is above a critical inductance value, the TBPR operates in a continuous conduction mode, the continuous conduction mode configured to cause a low ripple DC output relative to ripple of an AC input and thereby providing power factor correction.
