摘要： A power converter including a compressor as a load includes a compensation current output (80) allowing compensation current (Ic), which compensates for leakage current (Ia), to flow. A controller (50) receives a detection signal from a rotational speed sensor (55) which senses the rotational speed of the compressor (CM). When the rotational speed has increased to a set rotational speed at which the leakage current (Ia) is lower than or equal to its limiting value (Lmax) (e.g., the limiting value specified under the Electrical Appliances and Materials Safety Act or by the IEC) in a state where the compensation current output (80) is off, the compensation current output (80) is switched from an on state to an off state. This may reduce the leakage current from the compressor with low power loss.

摘要： A power supply apparatus having an AC power supply, a transformer, a switching element and a control circuit for controlling an operation of the switching element: where an electrical current is supplied to the primary side of the transformer intermittently when a main unit of an electrical appliance to which the power supply apparatus is applied is in a standby mode so that unnecessary power consumption is reduced. Further, a capacitance is provided between the AC power supply and the control circuit instead of the conventional initializing resistance and the control circuit is driven using an electrical current going through a reactance component of the capacitor, so that the energy loss is not caused any more by the initializing resistance.

摘要： A cathodic corrosion inhibiting apparatus is disclosed which is characterized by outputting a substantially square-wave rectified output from a AC input. The square-wave rectified output has a substantially constant DC component and a minimal AC component which allows the output to minimize large oscillations in electromotive potential about a DC mean associated with traditional rectified cathodic protection apparatus. The apparatus of this invention is also designed to be remotely monitored and controlled and can include self-monitoring and control circuitry to maintain a given degree of corrosion protection to a metallic apparatus.
