INVT GD350-CCS Series VFD for Electric Boat Propulsion System

Green Future, Intelligent Navigation of New Waterways

In this era of pursuing green and sustainable development, electric boats, as a green revolution in the field of water transportation, are gradually rewriting the history of traditional shipping. Electric boats, this emerging waterborne vehicle, with its significant characteristics of zero emissions, low noise, and environmental friendliness and energy conservation, directly converts the electrical energy stored in batteries into power, achieving the ultimate optimization of energy utilization, and has become an indispensable and important development direction for future water transportation.

Whether it's sightseeing boats navigating urban waterways or exploration vessels venturing into the open ocean, electric boats, with their unique green charm, add a refreshing touch of green to waterways around the world.

01 The Green Start of Electric Boats

Faced with the development trend of electric boats, customers have put forward higher requirements for the propulsion system:

1. Ensure stable power supply by providing power transfer and tiered protection for daily loads during power outages;

2. Utilize battery energy efficiently to extend the range;

3. Reduce interference from power electronic devices on the load to ensure stable equipment operation, etc.

02 INVT Solution: Innovation-Driven, Intelligent Future

Addressing customer needs and equipment characteristics, INVT leverages its deep industry experience and technological innovation to offer tailored solutions. By designing a perfect match between the motor's rated voltage and the battery voltage, full-power output is achieved across the entire voltage range. A unique drive algorithm effectively reduces VFD losses, improves battery energy utilization, and maintains efficient motor operation. Furthermore, INVT incorporates grid-connection algorithms and redundancy schemes to ensure the long-term parallel operation and stability of the daily-use inverter system, guaranteeing continuous and stable operation of electrical equipment even in the event of a single battery or system failure.

More importantly, INVT significantly reduces output-side harmonics through harmonic suppression algorithms, effectively minimizing interference from power electronic devices to daily loads and providing a stable and reliable power environment for shipboard equipment, ensuring worry-free navigation.
