An apparatus for controlling a compressor is provided. When grounding the apparatus for controlling a compressor, an analog circuit ground and a digital circuit ground may be insulated from each other to protect the apparatus. A ground of an analog circuit driven by commercial alternating current (AC) power, and a ground of a digital circuit driven by a voltage which has been converted from commercial AC power, may also be insulated from each other by a simple circuit device to protect a controller inside the digital circuit.

An apparatus and method for controlling a compressor are provided. An input voltage of a commercial power source, a motor voltage of a compressor motor, and a motor current of the compressor motor are detected, based on which voltage values of a capacitor and voltage values of a triac may be calculated. Thus, an additional operational amplifier or a sensor to measure a capacitor voltage is not required, reducing costs.

Provided are a novel transition metal complex where a monocyclopentadienyl ligand to which an amido group is introduced is coordinated, a catalyst composition including the same, and an olefin polymer using the catalyst composition. The transition metal complex has a pentagon ring structure having an amido group connected by a phenylene bridge in which a stable bond is formed in the vicinity of a metal site, and thus, a sterically hindered monomer can easily approach the transition metal complex. By using a catalyst composition including the transition metal complex, a linear low density polyolefin copolymer having a high molecular weight and a very low density polyolefin copolymer having a density of 0.910 g/cc or less can be produced in a polymerization of monomers having large steric hindrance. Further, the reactivity for the olefin monomer having large steric hindrance is excellent.
