Systems and methods for sending a power signal to a power switching device with galvanic isolation

A power electronics arrangement, comprising:

• a control stage, comprising:
• a power supply;
• and
• a controller;
• a switching stage, comprising:
• a receiver, filter, and converter (RFC);
• and
• a power switching device (PSD);
• and
• a waveguide;
• wherein an output signal is sent from the control stage to the switching stage via the waveguide, the RFC is configured to receive the output signal from the waveguide and convert the output signal into a switching signal and a power signal, the PSD is powered by the power signal and the PSD is controlled by the switching signal;
• the PSD comprises a transistor having a gate, and at least one of a low-side switch or a high-side switch, wherein the gate is controlled via the switching signal;
• and
• wherein the switching stage is galvanically isolated from the control stage.

A method for operating a power switching device (PSD), comprising:

• supplying, by a power supply, a power to a controller;
• converting, by the controller, the power into an output signal;
• guiding, by a waveguide, the output signal;
• receiving, by a receiver, filter, converter (RFC), the output signal, wherein the RFC is galvanically isolated from the controller;
• converting, by the RFC, the output signal into a power signal and a switching signal;
• and
• receiving, by a gate of the PSD, the switching signal;
• and
• powering, by the output signal, the PSD;
• wherein the PSD comprises a transistor having the gate, and at least one of a low-side switch or a high-side switch, wherein the gate is controlled via the switching signal.
