As the global energy landscape shifts toward renewable power and energy storage, Battery Energy Storage Systems (BESS) play a key role in stabilizing the grid, storing surplus energy, and improving power quality. One of the most critical components in any BESS is the Power Conversion System (PCS) — the heart of energy transformation between AC (grid) and DC (battery).
At TLS Energy, we understand that high conversion efficiency is not just a technical benchmark — it directly impacts the client’s operational cost, system reliability, and return on investment. That’s why we use advanced Silicon Carbide (SiC) IGBT technology in our PCS to ensure industry-leading efficiency and performance.
Real Performance: 99% Efficiency in Live Operation
In one of TLS Energy’s active projects, a screenshot of the PCS interface shows the following real-time values:
• DC Power: 3757 kW
• AC Power: 3795 kW
This indicates that only 38 kW is lost during the power conversion process — a conversion efficiency of approximately 99%. This level of performance is exceptional and far exceeds traditional power electronics.
This impressive result is made possible by the use of SiC-based IGBT modules in our PCS.
What is SiC IGBT Technology?
SiC IGBT stands for Silicon Carbide Insulated-Gate Bipolar Transistor. It is a type of power semiconductor device used to switch and convert electricity at high efficiency and high voltage. SiC IGBT is considered the next generation of power devices, offering significant performance improvements over traditional silicon-based IGBT.
Key advantages of SiC IGBT include:
• High Switching Frequency
SiC devices can switch at much higher frequencies with lower losses, enabling more precise and responsive control of power.
• Low Switching and Conduction Losses
SiC IGBTs reduce energy losses during switching operations, helping achieve high overall system efficiency.
• High Thermal Conductivity
SiC handles higher operating temperatures, which reduces the size of the cooling system and improves system reliability.
• Smaller and Lighter PCS Design
With less heat and more efficient performance, the PCS design becomes more compact, reducing container space and installation cost.
Why SiC IGBT Is More Efficient Than Traditional Si IGBT
To understand why SiC IGBT enables such high energy efficiency, it’s important to compare it with traditional silicon (Si) IGBT technology. Here’s a breakdown:

In photovoltaic (PV) power systems, the inverter plays a critical role in converting DC electricity from solar panels into AC power for grid use. At the heart of this conversion lies the IGBT (Insulated Gate Bipolar Transistor) module — a power device essential for high-efficiency switching. However, IGBT module failure, especially explosion due to stress or overheating, is a common and serious issue that can lead to equipment shutdowns or even fire hazards.
How IGBT Modules Work
IGBT modules are semiconductor devices that combine the benefits of MOSFETs and BJTs, offering fast switching speeds and low conduction loss. By controlling gate voltage, they switch on or off to regulate current flow and frequency. Their performance directly affects inverter efficiency and system reliability.
Common Causes of IGBT Failure
IGBT failure usually results from excessive internal heat or external electrical stress. Key reasons include:
1. Electrical Stress
•. Overvoltage: Transients like grid voltage spikes, lightning strikes, or reverse recovery voltage can exceed IGBT limits and cause dielectric breakdown.
•. Overcurrent: Sudden load changes, short circuits, or motor stalling may create current surges. If the protection circuit response is delayed (over 10µs), the module can overheat and rupture.
•. Drive Circuit Issues: Low gate voltage or signal noise can cause partial conduction, increasing power loss and local heat buildup.
2. Thermal Management Failures
•. Poor heat dissipation due to faulty fans, high ambient temperatures, or insufficient cooling can raise junction temperatures above safe limits (>150°C), causing material stress and eventual failure.
3. Design and Assembly Defects
•. Lack of buffer circuits, aged capacitors, or improper soldering and torque during installation can lead to increased contact resistance and heat.
4. External Factors and Human Error
•. Grid anomalies, unbalanced three-phase loads, or wiring mistakes can cause short circuits. Maintenance without proper ESD precautions can also damage sensitive components.
Emergency Handling After IGBT Failure
If an IGBT explosion occurs:
•. Shut down power immediately.
•. Inspect the system for smoke, fire, or visible damage.
•. Check driver voltages, DC bus capacitors, and absorption circuits.
•. Use a multimeter to verify if the IGBT is shorted.
•. Replace with a matching module, applying thermal paste and correct torque to ensure good contact.
Key Prevention Measures
•. Circuit Optimization: Use RC snubbers or TVS diodes to limit voltage spikes. Install fast fuses and current sensors for quick protection.
•. Proper Component Selection: Choose IGBTs with at least 2x voltage and sufficient current margin.
•. Enhanced Cooling: Use forced air or liquid cooling systems. Regularly clean heatsinks and verify fan operation.
•. Routine Monitoring: Use IR thermography and oscilloscopes to spot early faults. Design PCBs to minimize interference.
•. Staff Training: Educate operators on IGBT operation and failure modes. Install real-time monitoring to track temperature, voltage, and current.
IGBT failures in solar inverters are complex but preventable. By understanding the root causes and applying targeted design, monitoring, and maintenance strategies, system operators can reduce failure risk, extend equipment life, and ensure safer, more reliable PV operations.
