Systems and methods for control of zero-sequence stabilized power converters

Abstract

Disclosed are implementations that include a power converter system including a non-isolated N-phase DC/AC power converter, for N≥1, with a DC voltage section and an N-phase AC voltage section, with the power converter including energy storage arrangements for each of three phases of the AC voltage section. The energy storage arrangements are commonly electrically coupled to the terminals of the DC voltage section. The system further includes a controller to control voltages at the energy storage arrangements, with the controller including one or more switching devices to control voltages at one or more terminals of the energy storage arrangements, and at least one model predictive control (MPC) module to generate control signaling, based on electrical operational characteristics of at least some of storage elements, to actuate the one or more switching devices to establish zero sequence voltage stabilization behavior at the terminals of the energy storage arrangements.
