Bidirectional inverting piezo resonator-based (BIPR) converter for cell balancing applications

A novel piezo resonator-based resonant converter topology is presented, specifically tailored for active cell balancing applications. The bidirectional operation of the converter is presented, and the control requirements are discussed. Simulations are performed to determine the output voltage gain and output current of the converter. Finally, the cell balancing performance of the converter is simulated and compared to a passive balancing method, showing improved efficiency and balancing speed.
