Fundamentals of LLC resonant topology
Francesco Gennaro
LLC resonant control is widely used in medium power converters to achieve high
efficiency operation. Several design challenges must be addressed to achieve
optimum operation. This session will discuss techniques for these challenges
including, avoiding capacitive mode operation, optimizing dead time, and minimizing
noise during burst mode.
Evolution in PFC topologies
Gianni Vitale
Common topologies for PFC have evolved to improve the efficiency and power
factor at low loads. Analog techniques are often limited by the characteristics of the
controller devices and the technique chosen. The session will discuss the evolution
of the topologies and the control techniques from simple analog implementations to
digital techniques with advanced control. This session will also discuss all
variations of Transition Mode and Continuous conduction mode topologies that
includes Single stage PFC, Fixed-off-time and, Average current mode.
In-depth understanding of power MOSFET failure mechanisms
This presentation will help designers understand the common failures of power
MOS in various SMPS and Inverter topologies. Some guides will be presented to
predict which conditions are critical and how to avoid common design issues that
lead to failures.
Giovanni Tomasello
Concepts in digital power control
Gianni Vitale
Digital control of the regulation loop in power conversion offers several advantages
in terms of flexibility, programmable response, and improved efficiency. The
session will discuss implementation of digital control in power converters using the
latest control ICs with unique PWM control architectures.
Optimizing the flyback topology for efficiency and standby power
Francesco Gennaro
Energy efficiency and idle power waste are one of the biggest challenges for
engineers and our society. In this session, we will talk about ways of optimizing
efficiency for low power offline SMPS and strategies for minimizing output losses at
no load or zero load.

Primary side sensing techniques: design issues and implementation
Francesco Gennaro
Primary side sensing eliminates optocouplers and extra components required in
secondary side sensing which provides huge benefits in LED lighting applications.
The session discusses the implementation of primary side sensing control and
techniques to eliminate the errors introduced by the parasitic elements in the
transformer and secondary side components. The extension of the primary sensing
technology to non-isolated topologies such as Buck-Boost will also be presented.

Architectures for driving high brightness LED
Jianwen Shao
There are so many different topologies to drive high brightness LEDs. This session
will discuss how to select a suitable topology for different power levels of an LED
system and different performance requirements, such as dimming, power factor,
cost, etc. An innovative two stage soft switching primary side regulation topology for
high power (>100w) applications will be presented in detail.
Introduction to electronic drives for lighting applications and its standards
Jianwen Shao
LED lighting drivers come in several different configurations and the most
appropriate configuration depends on the specifics of the application. This session
will present an overview of different topologies commonly used in LED lighting
applications and aid the designer to select the topology most appropriate for the
application. Also, the most common industrial standards for LED drivers will be
covered. Engineers new to LED lighting applications will learn the tools to select and
specify the best solutions for their application.
Compatibility challenges for dimmers
New technology, such as LED and CFL lamps, causes tremendous compatibility
issues with traditional triac-based dimmers. Flicker is one of the main complaints
for consumers. This session will discuss the root causes of flickering. Another
challenge is how to supply more power for the controller from a 2-wire dimmer.
Possible solutions will also be discussed in this session.
Jianwen Shao
Design using on-line simulation
Thomas Hopkins
On-line simulation tools give designers tools to quickly design power conversion and
LED lighting circuits. These tools build on device manufacturers’ expertise of the
circuit and application and, therefor,e speed up the design. This presentation will
discuss using on-line simulations and will show a typical example.

Implementing sensorless field oriented control
Dennis Nolan
Sensorless field oriented control is becoming widely used in many motor control
applications. This session introduces concepts to implement sensorless control of
BLDC motors. The basics of vector control will be also be introduced and a
complete implementation with a dedicated advance timer in the microcontroller and
a power stage using the Integrated Power Modules will be demonstrated.
Improved Reliability in Motor Control Using Intelligent Power Modules
Giovanni Tomasello
Intelligent power modules incorporate the driver and power devices in a single
package. The package can also include thermal sensors that monitor the module
temperature. This presentation discusses using this temperature feedback and
shows a tool to accurately predict the actual die temperature so the system can be
guaranteed to work within the allowable range.
Using voltage mode for microstepping stepper motor drive
Thomas Hopkins
The performance of the stepper motor drive can be improved using voltage mode
drives, giving smoother operation and higher resolution. However, current mode
drives have typically been used, since they inherently compensate for increases in
the back EMF and variations in power supply voltages. This presentation discusses
techniques to compensate for these variations using voltage mode drives and
shows the implementation in easy-to-use controllers.
Isolated gate drivers for motor control
New GAP driver technology uses magnetic coupling to provide up to 4kV isolation
and high speed switching in a small IC package. The magnetic coupling allows
bidirectional transmission to get diagnostic feedback from the output stage. This
presentation shows implementations in motor control using the GAP driver
technology and the advantages of optocoupler isolation.

ST Lunch Keynote
Future of power semiconductor technology
This presentation will give a snapshot of state of semiconductors technology that is yet to come to market.
Future of power semiconductor is evolving at a pace that is faster than ever in its history. Digital divide in
the world of power is narrowing with introduction of digital controllers dedicated for power supply. After
many years of marginal improvements, diode technology is taking a leap with new FERD technology that
closes gap between diode rectification and synchronous rectification. Need for energy efficiency and
phantom power reduction is leading to introduction of innovative smart power supply switchers. With IGBT
based module adoption becoming a market standard, appliances are seeing an improvement in reliability
and cost of design. Silicon carbide process is opening new doors for high voltage and high frequency
application with introduction of >1200V switches. A very high level of view of newest semiconductor
technologies will be presented in this module.
