Advanced Shaft Generators

Traditional shaft generators connect directly to the main engine, running at fixed speed to maintain 50Hz output. They use straightforward synchronous machines with automatic voltage regulation, a proven technology that generations of engineers have relied on.

At Marine Hybrid Solutions, we understand these conventional systems can be transformed into versatile power sources through careful engineering.

Using a trawler conversion as an example, the existing generator can operate in two modes:

1.
Traditional fixed-speed 50 Hz operation using
a contactor setup

2.
Variable-speed mode, integrating with a compact
hybrid DC bus system to support both the
existing AC grid and high-power consumers,
such as winches with full bidirectional power flow

Optimized Power Electronics & Control

A variable-speed shaft generator requires power electronics and a transformer. The control system can be integrated into the existing Power ManagementSystem (PMS) or function as a standalone unit.
