Abstract
A coordinated fault-tolerant control method for a two-stage power module is provided. The two-stage power module includes a front-stage circuit and a rear-stage circuit. The front-stage circuit has a DC midpoint. Each of a first side circuit and a second side circuit of the rear-stage circuit includes two rear-stage switch sets. If one switch in one of the two rear-stage switch sets in the first side circuit fails, disable the other switch in the rear-stage switch set. Operate the other rear-stage switch set in the first side circuit normally. One of the two rear-stage switch sets in the second side circuit is operated normally, and the other of the two rear-stage switch sets in the second side circuit is disabled.
