Abstract: A power factor correction device for providing tolerance to a fault condition in an input supply can include a first boost circuit, a second boost circuit, and a controller circuit. The controller circuit can interleave operation of the first boost circuit and operation of the second boost circuit such as to generate an output voltage when the input supply is received at the power factor correction device. The controller circuit can route, in response to the fault condition, a stored supply of the second boost circuit to an input of the first boost circuit. The controller circuit can control the first boost circuit to maintain the output voltage.
