Saraswati Dynamics

Advanced IGBT-Based Full Bridge, Class-D Power Stage
At the heart of this power module lies an Insulated Gate Bipolar Transistor (IGBT)-based
full bridge, Class-D power stage. This configuration is capable of delivering up to
180VRMS and 150ARMS, ensuring robust and efficient power conversion. IGBTs are
renowned for their high efficiency and fast switching capabilities, making them ideal for
applications requiring rapid response and minimal power loss.

Comprehensive Communication and Monitoring via RS485 Interface
Equipped with an RS485 interface, the module facilitates seamless communication with Human-Machine Interface (HMI) displays. This allows for real-time monitoring and control of all operational parameters, enhancing system integration and user interaction.

Enhanced Signal Integrity with Differential Input Stage
The differential input stage utilises the latest generation surface-mount components to significantly reduce the Signal-to-Noise Ratio (SNR). This design choice ensures superior signal integrity, resulting in more accurate performance and reduced susceptibility to external noise.

Intuitive Status Indication and Diagnostics
Dedicated LEDs provide clear and immediate visualisation of the module's status and any error conditions. In the event of a failure, the module's digital address and specific error codes are displayed on integrated 7-segment displays, simplifying troubleshooting and maintenance processes.

Robust Monitoring and Rapid Interlock Response
All critical parameters, including voltages, currents, and temperatures, are continuously monitored. The module employs Complex Programmable Logic Device (CPLD) technology to ensure that any critical interlocks are detected, and operation is ceased within an ultra-fast response time of 15ns, protecting both the module and connected equipment.

Versatile Load Compatibility with Multi-Stage Output Filtering
A sophisticated multi-stage output filter, incorporating a Zobel Network, ensures impedance matching across a broad spectrum of loads—both resistive and inductive. This design guarantees stable and reliable operation, regardless of load characteristics.Adaptive Feedback Mechanism for Bus Voltage Fluctuations
The feedback stage is intricately designed to couple with the bus voltage, ensuring that any spikes or power failures do not result in abrupt changes in output power. This adaptive mechanism maintains consistent performance and protects downstream equipment from potential disturbances.

Thermal Management and Reliability
Efficient thermal management is a crucial factor in power module design, directly impacting performance and longevity. Our module utilises thick thermal pads to effectively isolate electrical connections from the heat sink while ensuring optimal heat dissipation.

To enhance stability and reliability, the heat sinks are precisely machined with dedicated slots to securely hold these thermal pads in place, preventing any displacement during operation or transportation. This design allows for the integration of large, continuous heat sinks along the entire length of the module, enabling uninterrupted, straight-line airflow for maximum cooling efficiency.

By minimising thermal resistance and ensuring consistent heat dissipation, this advanced cooling solution enhances operational stability, extends the lifespan of the module, and guarantees reliable performance even in demanding environments.

Wide Range of Applications
This 27kVA Power Module is ideally suited for various applications, including:
Renewable Energy Systems: Efficiently managing power conversion in solar and wind energy installations.
Industrial Motor Drives: Providing precise control and energy efficiency in motor drive applications.
Uninterruptible Power Supplies (UPS): Ensuring reliable backup power with rapid response times.
Electric Vehicle Charging Stations: Delivering high-power charging solutions with robust performance.

In summary, our 27kVA Power Module embodies the pinnacle of modern power electronics design, offering exceptional performance, reliability, and adaptability to meet the evolving demands of today's technological landscape.
