The present disclosure provides a system and method that provides active damping at the input of a motor drive system without the need for the hardware used in conventional and RC damping circuits. According to the disclosure a virtual damping network is realised at the input of the motor drive system based on modification of field-oriented control, FOC. More specifically, a control algorithm creates a virtual damping impedance at the motor drive input by applying a damping algorithm to both q and d components of the motor current.

A cargo handling system includes a power drive unit (PDU) configured to transport cargo within an aircraft. The cargo handling system further includes a cargo control unit (CCU) configured to output control data for controlling operation of the PDU. The cargo handling system further includes a power control unit (PCU) coupled to the PDU and the CCU. The PCU is designed to receive alternating current (AC) electrical power from a power source, convert the AC electrical power into direct current (DC) electrical power, receive the control data from the CCU, generate an output signal including the DC electrical power and the control data, and transmit the output signal to the PDU.

A power converter gate driver arrangement for providing a power output and a switching output for switching, in use, one or more switching devices, wherein the switching devices are controlled from a digital core via isolated point-to-point RF drivers. The gate driver uses UHF band technology to transmit both signal and power through a low capacitance single resonator by signal and power modulation. Power is transmitted in a continuous manner.

A power electronics arrangement may comprise a power supply, a controller configured to receive a power from the power supply and generate an output signal, a waveguide, a receiver, filter, and converter (RFC) configured to receive the output signal via the waveguide, the RFC configured to generate a switching signal from the output signal, and a power switching device (PSD) configured to receive the switching signal from the RFC, wherein the controller transmits the output signal to the RFC through the waveguide via a transponder, the waveguide is coupled between the transponder and the RFC, and the PSD is galvanically isolated from the power supply.
