Excessive Heating of IGBTs and How to Prevent It

The best way to protect electronic equipment from power disturbances is by using an Uninterruptible Power Supply (UPS). UPS systems are available in various sizes, from small desktop units that safeguard individual computers to large-scale systems capable of supplying power to entire buildings. During a power outage, a UPS provides backup power, allowing users to save data and safely shut down equipment while also conditioning and filtering the electrical supply.

UPS systems are essential across many industries, including hospitals, airports, data centers, oil and gas facilities, and manufacturing plants, where uninterrupted power is critical. Modern organizations rely on UPS solutions to protect their core operations from mains failures, voltage fluctuations, power surges, and other electrical disturbances, ensuring operational continuity and equipment safety.

In industrial applications, the choice between Rotary UPS and Static UPS systems has long been debated. While Rotary UPS systems remain popular for high-capacity installations exceeding 800 kVA, Static UPS solutions have gained significant market share in recent years. One key reason is cost, as Rotary UPS systems can be up to 30% more expensive than their Static counterparts, making Static UPS a more economical option for many organizations.

Advancements in power electronics have significantly improved the performance of Static UPS systems. Traditionally, these systems used thyristor-based inverters, but modern designs now incorporate Insulated Gate Bipolar Transistor (IGBT) technology. This transition has dramatically enhanced efficiency and the ability to handle non-linear loads, such as computers and Switched-Mode Power Supplies (SMPS), while maintaining exceptionally low voltage distortion.

Unlike thyristor technology, which often caused the peaks of the voltage waveform to flatten, IGBT-based inverters produce a cleaner and more stable output. Additional benefits include reduced inverter size, improved reliability, and easier maintenance. The compact design of IGBT modules allows for faster servicing and minimizes system downtime, making them ideal for mission-critical environments.

Furthermore, the integration of digital control systems and advancements in the IT sector have made remote monitoring and management of UPS systems simple and efficient. Operators can now supervise performance, receive alerts, and conduct diagnostics from remote locations—even from another country—enhancing system reliability and operational flexibility.

Rotor Position Sensor Systems for Brushless Motor Control Using IGBTs

Brushless motors are widely used in modern applications such as hybrid and electric vehicles (HEV/EV), where high efficiency and precise control are essential. These motors rely on accurate and fast rotor position sensor systems to ensure proper commutation. The performance of these sensors has a significant impact on motor startup behavior, dynamic response, torque ripple, and overall system efficiency, especially in IGBT-based motor control systems.

There are several methods for detecting rotor position, including electromechanical (inductive) sensing and magnetic sensing technologies. Traditional resolver-based sensor systems have been widely used, but they come with certain limitations such as analog signal output, complex circuitry, higher system cost, space constraints, sensitivity to stray magnetic fields, and strict positioning tolerances.

To address these challenges, advanced solutions such as the AURIX Microcontroller Family from Infineon Technologies provide an efficient alternative. These 32-bit microcontrollers feature integrated delta-sigma ADCs that enable carrier signal generation and software-based decoding. This integration eliminates the need for external resolver ICs, helping reduce system cost by up to 20% while simplifying design and improving reliability.

In addition, modern xMR (magneto-resistive) angle sensors, including AMR (Anisotropic Magneto-Resistance) and GMR (Giant Magneto-Resistance) technologies, offer high precision and improved robustness. These sensors provide accurate rotor position detection with lower sensitivity to mechanical tolerances and external interference, making them ideal for electric vehicle motor control and industrial automation systems.

The combination of IGBT-based inverters, advanced microcontrollers, and high-precision magnetic sensors enables efficient and reliable brushless motor control.
