The proliferation of small electric motors in robotics and unmanned aerial systems is creating demand for highly integrated and efficient motor-drive electronics. In the context of humanoid robot joints, robotic hands, and lightweight drone propulsion systems, we require power converters that have a high current density in very limited mechanical space.

The motors are usually characterized by low phase inductance and low winding resistance, so that the inverter switching performance is particularly important. Higher switching frequencies can enhance current regulation bandwidth and dynamic response and improve overall efficiency while reducing the size of passive components under these operating conditions.
