The disclosure concerns a totem pole PFC with a surge protection circuit, wherein the totem pole PFC comprises at least one bypass-diode branch with at least two bypass-diodes, at least one switch branch with at least two switches, at least one polarity changer branch with at least two switches, an input bridge connecting the switch branch(es) with an input voltage source, and at least one bypass branch connecting the input bridge in parallel with the bypass-diodes of the bypass-diode branch(es). The surge protection circuit comprises at least one current sensor configured to detect a current flowing through at least one of the bypass-diodes of the bypass-diode branch(es), and a control unit configured to receive a detected current value from the current sensor(s) and to switch at least one switch of the totem pole PFC at least in dependence on the detected current value.
A totem pole power factor correction circuit (PFC) with a surge protection circuit, comprising:
A surge protection method for a totem pole PFC, wherein the totem pole PFC comprises at least one bypass-diode branch with at least two bypass-diodes, at least one switch branch with at least two switches, at least one polarity changer branch with at least two switches, an input bridge connecting the switch branch(es) with an input voltage source, and at least one bypass branch connecting the input bridge in parallel with the bypass-diodes of the bypass-diode branch(es), the surge protection method comprising:
