This paper describes a volumetric
design study, which evaluates switching loss, thermal management and the physical dimensions of all major
passive components, including the electromagnetic interference (EMI) input
filter, boost inductors and DC-link
capacitors, for a three-phase low-voltage power factor correction (PFC) stage
for electric vehicle chargers. The proposed design study considers three popular
three-phase pulse width modulated (PWM) active front-end AC-DC topologies: the
standard 2-level industry solution, the 3-level neutral point clamped (NPC)
converter and the 3-level T-type (T²C) converter. For each topology, the
pulsating switched phase-leg voltages are computed for both continuous space
vector pulse width modulation (SVPWM) and 60° discontinuous pulse width
modulation (DPWM). Based on the switched phase-leg voltages, the impact of the modulation technique and switching frequency on
switching loss, heatsink and passive components is thoroughly analyzed. For an
accurate estimation of the switching loss, the switching energies of
state-of-the-art silicon carbide (SiC) MOSFETs have been measured at corresponding
operating points. Results are presented for an 11 kW, 800 V active power factor
correction (PFC) application.
