“…Around the zero-crossings, a LF ringing can be observed in the current, which is attributed to the transition between Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM). The resulting THD of the current is 6.9%, which is a typical value for a totem pole configuration at 20% partial load operation [13,53,54] (a reduction of the THD can be achieved with the concepts proposed in [55,56]). Furthermore, new EV charger designs typically require bidirectional operation; in that case, the LF bridge-leg is actively operated, which resolves the aforementioned issue.…”

New EV Battery Charger PFC Rectifier Front-End Allowing Full Power Delivery in 3-Phase and 1-Phase Operation

A new universal front-end PFC rectifier topology of a battery charger for Electric Vehicles (EVs) is proposed, which allows fast charging at rated and/or full power level in case of 3-phase (Europe) as well as 1-phase (USA) mains supply. In this regard, a conventional 3-phase PFC rectifier would facilitate only one-third of the rated power in case of 1-phase operation. The new topology is based on a two-level six-switch (2LB6) 3-phase boost-type PFC rectifier, which is extended with a diode bridge-leg and additional windings of the Common-Mode (CM) chokes of the EMI filter. Besides this extension of the power circuit, the general design of the new converter is explained, and the generated Differential Mode (DM) and Common Mode (CM) EMI disturbances are investigated for 3-phase and 1-phase operation, resulting in guidelines for the EMI filter design. The EMI performance (CISPR 11 class-B QP) is experimentally verified for 1-phase and 3-phase operation at an output power of 4.5 kW, using a full-scale hardware prototype that implements the proposed extensions for a 2LB6 3-phase boost-type PFC rectifier and that is designed for output power levels of 22 kW and 19 kW in case of 3-phase and 1-phase operation, respectively. Compared to a conventional 2LB6 PFC rectifier, the volume of the extended system increases from 2.7 dm3 to 3.4 dm3, of which 0.5 dm3 is due to the additional dc-link capacitance for buffering the power pulsation with twice the mains frequency occurring for 1-phase operation.

“…Even though operating in CRM with a soft-switching method can achieve valley/zero-voltage-switching or zero-current-switching, it is unappealing for higher power applications due to high zero-current-detection subcircuit cost, high EMI noise and high input current ripple. By exploiting more advanced figure-of-merits (FOM) of fast switching WBG power electronic devices such as SiC MOSFETs and GaN FETs to substitute the Si power semiconductors, the WBG device-based totem-pole bridgeless PFC rectifier has become practical for continuous conduction mode operation and improved the power density for the system [11,[18][19][20][21][22][23][24][25][26][27][28]. One of the modified versions of the totem-pole bridgeless PFC is implemented with a full-bridge configuration in synchronous rectification mode, comprising active H-bridge switches (Q 1 , Q 2 , Q 3 and Q 4 ), which reduces the power dissipation when compared to the equivalent diodes [25,28].…”

With the unceasing advancement of wide-bandgap (WBG) semiconductor technology, the minimal reverse-recovery charge Qrr and other more powerful natures of WBG transistors enable totem-pole bridgeless power factor correction to become a dominant solution for energy storage systems (ESS). This paper focuses on the design and implementation of a control structure for a totem-pole boost PFC with newfangled enhancement-mode gallium nitride field-effect transistors (eGaN FETs), not only to simplify the control implementation but also to achieve high power quality and efficiency. The converter is designed to convert a 90–264-VAC input to a 385-VDC output for a 2.6-kW output power. Lastly, to validate the methodology, an experimental prototype is characterized and fabricated. The uttermost efficiency at 230 VAC reaches 99.14%. The lowest total harmonic distortion in the current (ITHD) at high line condition (230 V) attains 1.52% while the power factor gains 0.9985.
