ON Semiconductor to Show Next Generation Power Systems in Action at APEC 2015
March 11 2015 - 12:12PM
Business Wire
LLC power supply, new developments in GaN, and
motor drive control demonstrations, in addition to major
involvement in the conference program
Applied Power Electronics Conference (APEC) – Booth 407
– ON Semiconductor (Nasdaq: ONNN), driving energy efficient
innovations, will be showcasing some of its latest advances in
power management technology at APEC, including a new LLC
current-mode power supply for computers and LED TVs, significant
developments in GaN, and a sensor-less motor driver controller.
Current-Mode LLC Power Supply
One of the demonstrations will include the industry’s first
current-mode LLC controller, the NCP1399, highlighting the safety
features and benefits inherent to a current-mode control approach.
The power supply reference design will incorporate the NCP1399
along with ON Semiconductor’s NCP4810 X2 capacitor discharger,
NCP1602 power factor controller, and NCP4305 synchronous
rectification controller. This system solution is predominantly
aimed at power supplies for all-in-one computers and large LED TVs,
as well as ultra-high density power adapters. It is capable of
achieving markedly higher performance, lower standby power and
higher power conversion efficiency levels than would be possible
using competitive devices. The current-mode control architecture of
the NCP1399 is the heart of the power supply reference design
bringing built-in protection features, faster transient response
and light load efficiency enhancements. The NCP4305 provides
improved efficiency with a large 8 A driver and built-in light load
detection.
Converter with GaN High-Electron-Mobility Transistors
(HEMTs)
A two-stage converter demonstrating the latest high-efficiency
results obtainable with GaN will also be featured at APEC. This 240
watt (W) supply achieves 95 percent peak efficiency with the
NCP1397 LLC controller, NCP1654 power factor correction controller,
and TPH3202PS or NTP8G202N GaN transistor switching devices. The
board utilizes GaN HEMTs in both the PFC stage and in the primary
side of the LLC stage.
Automotive Motor Driver
The motor driver demonstration showcases a next generation
software-less automotive motor driver solution, LV8907. On-chip
intelligent sensor-less commutation logic enables LV8907 to drive a
brushless DC (BLDC) motor without any position sensor, thereby
reducing the solution cost and footprint. This software-less
solution with on-chip configuration registers can be customized for
a wide range of motor and load combinations using an easy-to-use
and free graphical user interface (GUI) utility from ON
Semiconductor. LV8907 with pre-loaded configuration registers can
drive the motor in a stand-alone mode without an external system
controller. With an integrated LIN transceiver, LV8907 can also
deliver a LIN-based advanced motor drive solution using a small and
low cost companion controller that is required only for LIN
management tasks.
Additionally, ON Semiconductor technical experts will be giving
Professional Education Seminars at APEC 2015 as part of the
conference agenda:
- Christophe Basso, application
engineering director at ON Semiconductor, will present a seminar on
"Practical Implementation of Loop Control in Power Converters"
(March 16)
- Roger Stout, research scientist
at ON Semiconductor, will present a seminar on "Power Electronics
System Thermal Design" (March 16)
