<p>A hybrid diode-less power converter topology of the present invention converts power from an AC power source to a variable load with high efficiency. The power converter includes a non-symmetrical arrangement of rectifying switches (29, 30) for rectifying an input AC voltage and shaping switches (24, 25) for shaping an input AC current. The shaping switches are operated in CCM based on an input AC current. Operation of each of the rectifying switches and shaping switches are further controlled wherein a commutation time for the shaping switches is associated with a first voltage rise and fall time (e.g., less than 10ns), and a commutation time for the rectifying switches is associated with a second voltage rise and fall time (e.g., at least 100ns), wherein the first voltage rise and fall time is less than the second voltage rise and fall time by a factor of nine or more.</p> |
