Abstract: A DC to AC inverter has a DC power input port, a buck converter, a buck/boost converter, an output filter and an AC output port. The DC power input port has a positive input terminal and a negative input terminal, both connected to a DC source. The AC output port is connected to a single-phase utility system. When the single-phase utility system is in positive half cycle, the buck converter generates a positive half-cycle signal of sinusoidal current. When the single-phase utility system is in negative half cycle, the buck/boost converter generates a negative half-cycle signal of sinusoidal current. In either the positive or negative half cycles, only one power electronic switch is switched in high frequency to reduce switching loss. Further, the negative input terminal of the DC power input port of the invention can be connected to a neutral line of the single-phase utility system.

Abstract: A rotor mechanism of a centrifugal compressor connectable to a power output device and configured to block leakage of lubricants and to recycle lubricants to an oil sump is provided, which includes a rotary shaft with a rolling bearing and a screw nut, a bearing housing for receiving the rolling bearing, and a bearing plate connected to the bearing housing. The screw nut has a surface provided with an oil throw seal, and the bearing housing. As the bearing plate is provided with an oil channel in contact with the oil-returning hole and either one of the bearing housing and the bearing plate is provided with a first labyrinth seal in contact with the screw nut, lubricants leaking out of the rolling bearing is allowed to go to the oil sump via the oil channel and oil-returning hole. The oil slinger thus blocks the lubricants from leaking out of the first labyrinth seal.

Abstract: A method for predicting surge in a compressor is provided, which is applicable to a cooling apparatus equipped with a centrifugal compressor. A set of highest outlet pressure values is obtained by a performance test performed on the centrifugal compressor. A coolant flow rate value and an opening percentage value of inlet guide vanes of the centrifugal compressor are measured. An outlet pressure value of the centrifugal compressor is calculated with an equation using the measured coolant flow rate value and the measured opening percentage value. The outlet pressure value is compared with one of the highest outlet pressure values corresponding to the measured opening percentage value, and if the outlet pressure value is larger than or equal to the highest corresponding outlet pressure value, it confirms imminent surge in the centrifugal compressor, so as to provide a basis of preparation for surge elimination.
