400 Hz Inverter
The 400 Hz Inverter is a compact, high-performance static power conversion system developed to deliver reliable AC power in demanding aerospace, defense, and specialized industrial environments. The system operates from a 24 V DC input source and generates a regulated 115 V, 400 Hz AC output.
The inverter is built around a TI DSP-based real-time control platform, enabling precise waveform synthesis, fast transient response, and deterministic protection handling. Both the power stage and firmware architecture have been designed with a strong focus on robustness, reliability, and long-term maintainability.
With a rated output power of 1.2 kW and an overall system weight of approximately 2.2 kg, the inverter achieves an excellent power-to-weight ratio, making it suitable for applications where size, weight, and performance are critical constraints.
