We investigated small-scale hydraulic power system using a system level analysis, where small-scale refers to systems generating 10 to 100 Watts output power, to determine whether the high power density advantage of hydraulic power system holds at small sizes. Hydraulic system power density was analyzed with simple mathematical models and compared to an equivalent hypothetical electromecha-nical system constructed from high-end off-the-shelf components. Calculation results revealed that high operating pressures are needed for smallscale hydraulic power systems to be lighter than the equivalent electromechanical system.
