Abstract
A driver circuit for a PFC cell is described. The PFC cell has a half-bridge with two half-bridge switches connected via a connection point. A star point switch connects the connection point to a star point of the PFC cell. The driver circuit has a target control signal input for target actuation signals and two half-bridge drivers connected downstream. The half-bridge drivers are configured to transmit signals from the inputs to the outputs only when they are not both in the HIGH state. The first output of the first half-bridge driver is connected to a control output of the driver circuit for the star point switch. At least one input of the second half-bridge driver is connected downstream of the second output of the first half-bridge driver. Two outputs of the second half-bridge driver are connected to control outputs of the driver circuit for the two half-bridge switches.
