There is a need to drive a wide variety of electrical loads, including capacitive loads such as piezoelectric actuators, that operate at high voltages and draw large currents, while minimizing electrical noise. At such high operating power levels, electrical efficiency is crucial.
The solution is to replace the transformer-based power stage with a high specific charge capacity battery-based power stage. This provides electrical isolation resulting in minimal noise. The internal battery configuration is flexible and adjustable while in operation, allowing optimal power output over a wide range of operating conditions. The high specific charge capacity allows high power density resulting in a small form factor.
- Battery-based Power Supply: The use of a battery-based power supply ensures a noise-free, clean power supply, isolated from supply mains, enhancing safety and efficiency.
- High Efficiency: The system significantly reduces heat dissipation and allows for a higher power density and larger current output.
- User-selectable Voltage Output: Users can select the voltage output, improving efficiency by limiting excess power dissipation.
- Portable Design: The unit is self-contained and portable, enabling deployment in otherwise unserviceable locations.
- Automated Battery Health Monitoring: Software and hardware monitor battery health, detecting weak batteries for timely action.
- Modular Battery Banks: Modular design allows easy swapping of battery banks, minimizing downtime.
- Computer Interface: A computer interface enables performance monitoring and control of the battery management system via a virtual instrument-based system.
Typical operative regimes are 150 – 200 V and 1 – 10 A, translating to 150 – 2000 W power. Typical AC-to-DC transformer-based solutions are severely limited by their maximum achievable power levels, leading to a compromise either on voltage or current.
Pilot or full scale system demonstration in an operational environment. The scheme is relatively inexpensive and employs COTS components. Due to the large demand and market for these components, the unit prices are already low and are projected to be even more competitive. The several practical advantages, as well as the ability to push the performance barriers, promise to open up several hitherto unexplored applications for this product. The commercial applications range from consumer electronics to heavy industrial equipment. The product also finds use in academia and R&D laboratories. It is a niche market with very few suppliers and large margins.
