GaN Switching Frequency: Using Gallium Nitride Technology in Next-Generation High-Frequency Circuits

Renee Yawger, Director of Marketing

Gallium nitride (GaN) is a very hard, mechanically stable wide bandgap semiconductor that is used in the production of power devices as well as RF components and light-emitting diodes (LEDs). GaN switching frequency is substantially higher than silicon, enabling power electronics designers to create smaller, more efficient, and higher-performing systems that were previously challenging to achieve with silicon technologies.

Shrink Motor Drives for eBikes and Drones

Marco Palma, Director of Motor Drives Systems and Applications

GaN is a game changer for motor drive applications. For designers to take advantage of this technology, fast and reliable time-to-market is critical. Easy-to-use reference designs using state-of-the-art electronics and techniques provide a valuable tool to speed time to market. The EPC9173 tool allows designers of eBikes and drones to enhance motor system size, performance, range, precision, and torque, all while simplifying design for faster time-to-market.  

The EPC9173 integrates all the necessary circuits to operate a 3-phase BLDC motor with high performance, 48 V input, 1.5kW output, and three-phase inverter using six EPC23101  GaN ICs. Thanks to the high-power density and the high electrical conductivity of GaN ICs, the EPC9173 delivers up to 25 ARMS on each leg and supports PWM switching frequencies up to 250 kHz under a natural convection passive heatsink. The resultant quality of the current output waveforms, lesser torque oscillations, and total system efficiency increase the performance of the motor-drive system. Further, the extremely small size of this inverter allows integration into the motor housing resulting in the lowest EMI, highest density, and lowest weight.

Motor Drives Showdown – GaN vs. Silicon

Marco Palma, Director of Motor Drives Systems and Applications

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.

How GaN is Revolutionizing Motor Drive Applications

Marco Palma, Director of Motor Drives Systems and Applications

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.

Reduce Audible Noise in Motor Drive Designs Using eGaN FETs and ICs

Renee Yawger, Director of Marketing

Brushless DC (BLDC) motors are popular and finding increasing application in robotics, e-mobility, and drones. Such applications have special requirements such as lightweight, small size, low torque ripple, low audible noise, and extreme precision control.  To address these needs, the inverters powering the motors need to operate at higher frequency but require advanced techniques to reduce the resultant higher power loss. Enhancement-mode gallium nitride (eGaN ®) transistors and integrated circuits offer the ability to operate at much higher frequencies without incurring significant losses.

ePower™ Stage – Redefining Power Conversion

Renee Yawger, Director of Marketing

Beyond just performance and cost improvement, the most significant opportunity for GaN technology to impact the power conversion market comes from its intrinsic ability to integrate multiple devices on the same substrate. GaN technology, as opposed to standard silicon IC technology, allows designers to implement monolithic power systems on a single chip in a more straightforward and cost-effective way.

Today, the most common building block used in power conversion is the half bridge. In 2014, EPC introduced a family of integrated half-bridge devices which became the starting point for the journey towards a power system-on-a-chip. This trend was expanded with the introduction of the EPC2107 and EPC2108, which integrated half bridges with integrated synchronous bootstrap. In 2018 we further continued the integration path with the introduction of eGaN ICs combining gate drivers with high-frequency GaN FETs in a single chip for improved efficiency, reduced size, and lower cost. Now, the ePower™ Stage IC family redefines power conversion by integrating all functions in a single GaN-on-Si integrated circuit at higher voltages and higher frequency levels beyond the reach of silicon.
