Abstract

For traditional linear Stirling Cryocoolers, the amplitude of output sinusoidal AC voltage is modulated mainly by Modulation ratio (M) controlled by the inverter, so that the compression piston is driven to perform linear reciprocating motion and the compressed refrigerant expands rapidly in the expander to achieve the purpose of refrigeration. In practice, however, when M is used to modulate the amplitude of sinusoidal AC voltage, the input power and current will increase to a certain extent with the decreased M. To address the aforementioned concern, the correlated characteristics of output voltage of the inverter under the M and vector phase shift modes will be compared and analyzed in this paper for the selection of best driving mode for linear Stirling cryocoolers. Although the experiments reveal a small difference of sinusoidal voltage amplitude of the two modes under the same input voltage, and a basically same energy distribution of waveform at the fundamental frequency and other frequency multiplications, the required power and current are more stable and do not increase with the decreased output voltage amplitude in the mode of vector phase shift.
