What is a Cycloconverter? The Honda Cycloconverter Series produce multiphase, high voltage AC (alternating current) and then processes (converts) it through the Cycloconverter unit into a stable single phase 240 Volt AC power. At the heart of the all new Honda Cycloconverter Series is a unique new generator system featuring a special high-speed multi-pole alternator integrated into the engine itself. Honda got rid of the bulky flywheel usually attached to the engine and replaced it with this unique alternator and Cycloconverter, effectively reducing the overall weight and size by approximately 30%.
