Master's Thesis
It is with great pride that Mr. Bisson submitted his master’s thesis to the École de technologie supérieure (ÉTS), entitled “Design of a resonant converter for a permanent magnet synchronous machine”. This ambitious project was the result of several years of in-depth research and hard work, aimed at optimizing the performance of permanent magnet synchronous machines, which play a crucial role in many industrial applications.
Mr. Bisson is honored to have received an honorable mention for this work, which is a testament to the impact and quality of his research. This success would not have been possible without the support of his research director Kamal Al-Haddad and his family who encouraged him throughout this journey.

Floating Motor Neutral Works Just Fine
Previous publications of the electric drive topology shown that the motor’s wye neutral point was equipotential with the zero Volt reference of the bipolar battery. In the early stages of development there was a need to simplify the calculation and simulation for the proof of concept. Connecting the motor neutral to the zero volt reference allowed to electrically isolate each phase and therefore control the phase current without interferring with the other phases. Improvements to the model allowed to fix the sum of phase currents to zero, therefore eliminating the need for the lead between the bipolar battery’s ground and the motor neutral.
Without any change to the inverter or Capacitive Boost Processor topologies, isolating the motor’s wye neutral actually provides a smoother phase to neutral voltage profile, which in turns provides a smoother phase current. The phase currents are also better balanced.
No modification to the control algorithm was needed either. The control algorithm operates in closed loop, and therefore is able to adjust the inverter output voltage to achieve the desired current amplitude and phase.
The graphic on the right shows the phase to neutral voltage (combined inverter and capacitor voltages) with a floating motor neutral and a zero volt (grounded) motor neutral.
