PROTECTION METHOD, SYSTEM AND APPARATUS FOR A POWER CONVERTER |
摘要 |
Among many embodiments, a power converter and a method for operating a power converter are disclosed. The power converter may include a pair of switches connected in scries, an output transformer connected to a common node between the switches and a protection apparatus for protecting each switch from being hard driven, each switch being enabled by a gate signal and turning ON in alternating half cycles so as to drive transformer current in alternate directions through the transformer. The protection apparatus may include: a detector configured to detect whether an intrinsic diode in a first switch is conducting the transformer current; and a gate signal disabler configured in response to the detector blocking an ON gate pulse from reaching a second switch in the pair of switches so that the second switch is not turned ON while the intrinsic diode of the first switch is conducting. |
