Non-linear control of a paralleled half-bridge complementary-control converter system with a single-wire current sharing

This paper proposes the design of a non-linear control of paralleled half-bridge with complementary-control (HBCC) converters. A large-signal model of the paralleled system is presented in order to deduce the non-linear control structure that is applied to the converters. Current sharing among converters is achieved by using a single-wire current-share scheme. The control behavior of the system has been tested with proper simulations for the paralleled system.
