- This paper investigates how the losses in a Free Piston Energy Converter during start, stop and idling affects energy consumption and required power from the supply system. Simulation results indicate that the electrical machine efficiency is the most critical factor during start. Moreover, by choosing the correct amplitude of the starting force, energy consumption during start can be reduced. When it comes to idling, friction is the most significant loss factor. Nevertheless, by compensating the mechanical loss for short time intervals using the generator force, the reciprocating motion can be kept alive for a rapid start without major energy consumption.
