Ultra-compact and highly efficient battery-powered LV motor drives based on GaN
The ultimate combination for next-level motor control designs: CoolGaN™ Transistors and PSOC™ Control C3 MCUs
The increasing demand for battery-powered low-voltage motors (<200 V) across various applications, including commercial drones, humanoids, mobile robots, and cobots, can be attributed to several trends, one of them being the aging population, which requires assistive technologies that can aid our daily lives. Battery-powered motors play a crucial role in powering these technologies.
Another significant factor is the rise of automation in industries, where companies are turning to robots and automated systems to increase efficiency and productivity. Additionally, the growing focus on sustainability and environmental protection is driving the adoption of battery-powered motors, which offer lower emissions and energy efficiency.
To address the growing demand for increased performance and higher efficiency, motor controls with higher switching frequencies can be employed. This approach can reduce size, weight, and audible noise while extending battery life. A powerful solution for efficient power management in battery-powered low-voltage motor drive applications can be achieved by pairing CoolGaN™ Transistors with PSOC™ Control C3 microcontrollers. The high-speed switching capabilities of CoolGaN™ are complemented by the flexible and configurable control offered by the PSOC™ Control C3.

CoolGaN™ Transistors 100 V G3
Infineon’s 100 V GaN transistors are normally-off e-mode devices housed in small packages such as PQFN 3x3, PQFN 3x5 and come with very low on-state resistances, making them a great solution for high-speed or high-frequency switching applications. GaN transistors can be operated with reduced deadtimes, which results in a higher efficiency and enables passive cooling. Operation at high switching frequencies allows the quantity of passive components to shrink, which improves system density and reliability.
System benefits
Small and light
- Smaller bulk capacitance - capacitance defined in most cases by DC bus ripple – possible usage of only ceramic (smaller ESR)
- Lower overall inverter losses (switching, driver, etc.) allows heatsink size reduction
- Enables integration of drive + motor
Fast and accurate
- Typ. fCtrl_loop ≤ fPWM resulting in higher control loop bandwidth and hence faster motor response
- Lower torque ripple enables accurate motion applications
Cool
- Less heat generated thanks to low switching losses
- Lower motor temperature or more output power at the same temperature
- Ideal for temperature-critical designs (e.g., touchable surfaces)
Highly efficient
- Fast switching frequency resulting in higher efficiency
- Reduced bus capacitor ESR losses
- Increased battery life

Compact inverter reference design for low-voltage battery applications
The REF_MTR_48V30A_GaN reference design was developed to demonstrate the high power densities achievable within a small size of only 29 x 51 x 9 mm. This is thanks to the reduction of bulk capacitance and the high switching frequency operation (≥100 kHz) of the inverter without a big power loss penalty. Moreover, the twelve CoolGaN™ Transistors 100 V IGC033S10S1 provide a dual-side cooled device on an exposed-die PQFN package that can efficiently extract heat and provide more space for top-bottom PCB implementation.
