摘要： A converter includes a converter circuit 1 having a plurality of bridge-connected semiconductor switching devices for converting AC power into DC power, a smoothing condenser connected in parallel to the DC side of the converter circuit and a current detector provided in a condenser circuit to control a condenser current flowing through the smoothing condenser to be a set value. The condenser current is controlled to be the set value (e.g. zero) to thereby reduce the capacity of the smoothing condenser and make the converter small.

摘要： A refrigerating apparatus having a refrigerating cycle that comprises a compressor, an electric motor that drives the compressor, and an inverter device that variably controls the operating frequency of the electric motor. The inverter device includes a converter circuit that converts an A.C. voltage from an A.C. power supply into a D.C. current, an inverter circuit comprising a D.C./A.C converter, and a shunt resistance that detects a D.C. current flowing through a switching element of the inverter circuit. The shunt resistance detects a D.C. current, and the detected D.C. current value is calculated as a sine wave A.C. current for the electric motor in relation to action of the switching element.
