Power Converters for EV Charging (EE698E)
The charging system
of an electric vehicle (EV) is a crucial part of the
overall EV system. This course is designed to develop
the foundation for pursuing future research on the EV
charging system. The primary focus of this
course is the analysis, design, modeling, and control
of standard power electronic converters for the EV
charger.
The electrical
subsystems of an Electric Vehicle (EV) are 1)
battery charger and 2) motor drives. This course
will focus on understanding different power
electronic converters for EV chargers. The EV
chargers can be classified in several ways based on
1) the power levels, 2) charger location- onboard or
off-board, 3) isolated or non-isolated, 4)
unidirectional or bidirectional, and 5) conductive
or wireless-inductive. Generally, these chargers
have two power conversion stages- 1) power factor
corrected rectifier(PFC) for converting
line-frequency AC to DC, and 2) DC-DC power
conversion to charge the battery while providing
galvanic isolation. The second part could either be
conductive or wireless-inductive.
The first half of this course is designed to
understand the individual power conversion stages of
a conventional conductive charging system. A
boost-derived PFC circuit will be studied to provide
a clear understanding of the PFC stage. An
isolated H-bridge converter with phase-shift control
will be studied for the DC-DC power conversion
stage.
The remaining half of this course will explore
inductive wireless power transfer (WPT) technology
for EV charging. From the Power Engineering side,
WPT is relatively new, and only a limited course
reference material is available till date.
Therefore, all the basics of this technology will be
taught first. This includes basics of resonant
converter, WPT working principle, dual-side
compensation, circuit design, modeling, and
closed-loop control.
