This scientist got his Ph.D 40 years ago who saved the world's 15% energy consumption at one time. He is continuing his journey of innovations now in discovering silicon's replacement material for humankind.

My father always taught me that the true worth of an individual is measured based on their contribution to society. As I entered graduate school in 1975 I knew my passion was in the field of semiconductors, and I felt my best contribution to society would come from finding a successor to silicon. I did my graduate work in Gallium Arsenide, but realized by the time I received my PhD in 1977 that Gallium Arsenide’s prospects were limited as a semiconductor due to the basic materials properties, I went to work applying everything I learned to making better devices in silicon.

Mr. Krueger to direct EPC’s European sales organization and assist customers in adopting eGaN^® FETs and Integrated Circuits for leading-edge power conversion systems

EL SEGUNDO, Calif. — June 2017 — To support its accelerating growth, Efficient Power Conversion Corporation (EPC) is proud to announce that Wolfram Krueger has joined the EPC leadership team as Vice President of European sales. Mr. Krueger has over 30 years of sales operation experience within the semiconductor industry. His primary responsibilities at EPC are creating and implementing sales and marketing strategies to achieve the company’s sales objectives throughout Europe. He is based in Cologne, Germany.

With the current maturity of Class-D audio amplifier architectures, amplifier fidelity and efficiency limitations are primarily at the device level. Silicon MOSFETs have been evolving for almost forty years, and their progress towards a perfect switch has slowed dramatically. There are some fundamental characteristics of MOSFETs that degrade sound quality and efficiency. In 2010, the enhancement mode Gallium nitride (GaN) power FET was introduced by Efficient Power Conversion (EPC), providing a large step towards the perfect switch.

Taking advantage of the high performance of eGaN^® FETs, Rompower Energy Systems has announced a reference design for a tiny, 65 W, 94% efficient AC/DC power adaptor for laptops and other mobile devices.

TUCSON, Az. – June 2017 – Rompower Energy Systems, an internationally recognized research and development company in the field of power conversion, announces the availability of technology for an extremely small, highly efficient AC/DC power adapter. In the quest for higher power density, the efficiency of the adapter is critical in order to decrease the heat dissipation. The reference design is measuring just 3.19 cubic inches in size, this adapter provides 65 W of power at greater than 94% efficiency over the entire input voltage range (90 V_ac – 264 V_ac).  The adapter has a power density of 20 W/in³. This high efficiency means that the device runs cooler than standard AC/DC adapters.

EPC2111 GaN half bridge offers power systems designers a solution that increases efficiency for complete overall point-of-load system applications over 85% at 14 A when switching at 5 MHz and over 80% when switching at 10 MHz and converting from 12 V to 1.8 V.

EL SEGUNDO, Calif. — June2017 — EPC announces the EPC2111, 30 V enhancement-mode monolithic GaN transistor half bridge. By integrating two eGaN^® power FETs into a single device, interconnect inductances and the interstitial space needed on the PCB are eliminated.  This increases both efficiency (especially at higher frequencies) and power density, while reducing assembly costs to the end user’s power conversion system. The EPC2111 is ideal for high frequency 12 V to point-of-load DC-DC conversion.

During last week's PCIM Europe event in Nuremberg, Germany, direct 48V-to-1V power conversion architectures were a significant topic. “The use of GaN switches in 48V-to-1V direct dc-dc converters can improve system performance by 30%, compared with today’s best silicon-based designs,” commented Alex Lidow, CEO of Efficient Power Conversion.

EPC2046 GaN power transistor offers power systems designers a 200 V, 25 mΩ power transistor about 12 times smaller than equivalently rated silicon MOSFETs for wireless power, multi-level AC-DC power supplies, robotics, and solar micro inverters.

EL SEGUNDO, Calif. — May 2017 — EPC announces the EPC2046 power transistor for use in applications including wireless power, multi-level AC-DC power supplies, robotics, solar micro inverters, and low inductance motor drives. The EPC2046 has a voltage rating of 200 V and maximum R_DS(on) of 25 mΩ with a 55 A pulsed output current.

Wireless charging is not a new topic—it has been talked about for quite a while. Unfortunately, it has not seen widespread consumer acceptance. But, with a recently developed innovative approach to the design of transmission coils, wireless power is ready for widespread application.

Gallium nitride (GaN) power transistors designed for efficient power conversion have been in production for seven years. New markets, such as light detection and ranging, envelope tracking, and wireless charging, have emerged due to the superior switching speed of GaN. These markets have enabled GaN products to achieve significant volumes, low production costs, and an enviable reliability reputation. All of this provides adequate incentive for the more conservative design engineers in applications such as dc–dc converters, ac–dc converters, and automotive to start their evaluation process. So what are the remaining barriers to the conversion of the US$12 billion silicon power metal–oxide–semiconductor field-effect transistor (MOSFET) market? In a word: confidence.

I was led to believe we were heading for a wireless world but a look behind my TV tells a very different story when I see all those wires everywhere. Not to mention the increasing number of BRIDGES for IoT devices. We were hoping to talk about the wireless powered home and how GaN (gallium nitride) is making that possible! When it comes to gallium nitride, there is only one man to speak with, and he's truly changing the world at EPC. He first appeared on EP180 talking about Why Gallium Nitride Is About To Disrupt Silicon then returned on 203 The LIDAR Technology Behind An X-Ray Pill. But he has returned to today to talk about how it can wireless charge anything, and it will blow your mind. Dr. Alex Lidow, is the CEO and co-founder of Efficient Power Conversion and he is going to talk about how tech will make power cords disappear and how EPC is leading the charge in the wireless space.
