“…In some non-isolated converters, a percentage of the energy is transferred directly from the input to the output and does not need to be stored in reactive elements, but the rest of energy needs to be processed, meaning that it has to be stored and released by reactive elements [12] - [15]. Examples of that are buck or boost converters where the current flows directly from the input to the output during certain phase of the operation without processing the energy [12], [13].…”

“…One option is to utilize the buck/boost based DC to DC converter as an Active Voltage Regulator (AVR) [13]- [16]. However, these types of AVRs significantly decrease the efficiency of the converter, undermining the motivation for utilizing the PPRC in the first place [17], [18]. Another possibility is to utilize the Dual-Active-Bridge (DAB) DC to DC converter [19], or Resonant Switched-Capacitor Converter (RSCC) [20], in which case the voltages of the split DC bus can be regulated with the phase-shift control.…”

Certain modern power electronics systems require active regulation of the split DC bus capacitor voltages. The series resonant converter is suitable to be utilized as an active voltage regulator, due to its ability to operate with soft switching, and hence, with high efficiency. In discontinuous conduction mode, the series resonant converter operates with a constant unity voltage gain, thus achieving balancing of the DC link. However, discontinuous conduction mode does not provide means for achieving a different voltage distribution, which is important in many scenarios. On the other hand, by operating in quantum mode (i.e. type 2 discontinuous conduction mode), the voltages across DC bus capacitor can be regulated. Therefore, the modeling of the quantum mode series resonant converter connected across split DC bus is presented in this paper. The steady-state operation as well as transient behavior are discussed and experimentally verified on a laboratory prototype.INDEX TERMS active voltage balancing, partial power rated converters, quantum mode series resonant converter, soft switching, switched capacitor converter, zero current switching I.
