A multi-drive system based on a two-stage matrix converter

Multi-drive systems can be used in situations where several motors are mechanically connected. Such systems have applications in both industrial and aerospace applications, where they can be used to provide system redundancy. In conventional systems the power converter for the motor drive is based on a rectifier and inverter, leading to the requirement for large passive components such as DC-link capacitors. This paper proposes a multi-drive system based on a two-stage direct power converter. In this topology a direct converter uses two output stages with a single input bridge, eliminating the need for large passive components. Simulation results are included to demonstrate the feasibility of the proposed topology.
