APEC is The Premier Global Event in Applied Power Electronics

Preparations are well underway for EPC to head to Houston for the Applied Power Electronics Conference (APEC). The team is excited to be back, in-person exhibiting a large variety of demonstrations showcasing how the superior performance of GaN is transforming the delivery of power across many industries, including computing, communications, and e-mobility.

Here’s a sneak peek at some of the key application areas we will be showcasing in Booth 1302 at APEC.

The 48 V/12 V Automotive Evaluation Power Modules (EPC9137, EPC9163, EPC9165) Utilize the Two-Phase Synchronous Buck/Boost Topology

The 48 V/12 V automotive evaluation power modules (EPC9137, EPC9163, EPC9165, etc) utilize the two-phase synchronous buck/boost topology. The edge connectors and controller card are also designed to operate two modules in parallel with one controller, effectively achieving four-phase and therefore double the rated current and power. An example using EPC9137 modules are shown in Figure 1.

Motor Drives Showdown – GaN vs. Silicon

This GaN Talk blog discusses the advantages of using GaN-based inverters instead of silicon-based inverters for motor drive designs to operate smoother while reducing size and weight. These advantages are critical for motor drives used in typical applications such as warehousing & logistical robots, servo drives, e-bikes & e-scooters,  collaborative and low voltage robots and medical robotics, industrial drones, and automotive motors.

Omdia forecasts that worldwide shipments of warehousing and logistics robots will grow rapidly over the next 5 years from 194,000 units in 2018 to 938,000 units annually by 2022, with the rate of growth slowing after 2021 as many major players will have adopted robotic systems by then.  Worldwide revenue for this category will increase from $8.3 billion in 2018 to $30.8 billion in 2022, providing significant opportunities for established participants and emerging players.

Rethinking the Ordinary and Overcoming Mental Biases

Motor drive applications span several markets: industrial, appliance, and automotive. A commonality that occurs regardless of market is that when a new technology is proposed, it faces resistance to its adoption; after all, it is human nature to stick with what is known and resist change.

How to Design a Bi-Directional 1/16th Brick 48 V-12 V Converter Using Monolithic GaN ePower™ Stage

How to Design a Bi-Directional 1/16th Brick 48 V-12 V Converter Using Monolithic GaN ePower™ Stage
Dec 15 2020

Brick DC-DC converters are widely used in data center, telecommunication and automotive applications, converting a nominal 48 V bus to (or from) a nominal 12 V bus. Advances in GaN integrated circuit (IC) technology have enabled the integration of the half bridge and gate drivers, resulting in a single chip solution that simplifies layout, minimizes area, and reduces cost.

This application note discusses the design of a digitally controlled bi-directional 1/16th brick converter using the integrated GaN power stage for 48 V-to-12 V application, with up to 300 W output power, and peak efficiency of 95%.

The standard dimension of the 1/16th brick converter is 33 x 22.9 mm (1.3 x 0.9 inch). The height limit for this design is set to 10 mm (0.4 inch).

2020 New Year with GaN

2020 New Year with GaN
Jan 02 2020

Dear Friends, colleagues and partners of EPC,

Happy New Year to you and your family from all of us at EPC!

2019 was a year to remember for EPC’s GaN innovations and the multiple use cases for GaN that have come to fruition. EPC’s latest generation of GaN products have enabled engineers to gain power stage advantages due to their low RDS(on) characteristics, higher efficiency, enhanced thermal properties, small size and low cost. Now, more than ever, power system designers are switching from silicon devices to higher performance GaN components.

The Time for Disruption is Now − GaN Makes a Frontal Attack on Silicon Power MOSFETs

The Time for Disruption is Now − GaN Makes a Frontal Attack on Silicon Power MOSFETs
Nov 12 2019

Silicon has been around long enough. It’s time for a younger and far more fit challenger to take over semiconductor material dominance.

When I first started developing power devices 44 years ago, the “king of the hill” was the silicon power bipolar transistor.  In 1978 International Rectifier (IRF) launched power MOSFETs as a faster alternative to the slower and aging bipolar devices.  The early adopters of the power MOSFET were applications where the bipolar just was not fast enough.  The signature example for its adoption was the switching power supply for the desktop computer; first at Apple, and then at IBM
