发明名称 Linear compressor control circuit to control frequency based on the piston position of the linear compressor
摘要 A linear compressor operating apparatus includes a rectifying and filtering unit for converting an alternating current into a direct current, an inverter for inverting the direct current outputted from the rectifying and filtering unit into a desired frequency alternating current for operating a linear compressor in accordance with the alternating current outputted from the inverter, a position sensor for detecting a position of a piston of the linear compressor and outputting a position signal in accordance with said detection, a current detector for detecting the current running through the linear compressor, and a controller for receiving a current signal outputted from the current detector and a position signal outputted from the position sensor and outputting a pulse width modulating signal to control the inverter. The apparatus obtains a constant value of an interval which determines the efficiency of the linear compressor, regardless of a load thereof and optimizes a phase angle between the driving current and the compressor piston.
