1. An apparatus comprising:
a switching module that controls switching for two pairs of switches configured in an H-bridge in a switching power converter, the switching module controlling each of the two pairs of switches closed and opened based on a duty cycle control technique, the switching module closing and opening each switch of the two pairs of switches in a switching sequence, wherein the two pairs of switches connect to a positive terminal and a negative terminal of a direct current (“DC”) voltage source, and wherein for a first switching sequence a first switch of a pair of switches of the two pairs of switches has a higher switching power loss than a second switch of the pair of switches; a switch rotation module that changes the switching sequence of the two pairs of switches from the first switching sequence to a second switching sequence wherein the second switch of a pair of switches of the two pairs of switches has a higher switching power loss than the first switch of the pair of switches during the second switching sequence; and a switch wear module that tracks switching sequences, wherein the switch rotation module changes the switching sequence based on tracking of the switching sequences. |
