Low-frequency converters of frequency for asynchronous engine

2008 Third International Forum on Strategic Technologies, 2008
Nowadays the three phase electric engines, which supply from one phase voltage, have been getting to be widespread. The frequency method is the most efficient and effective method at the frequency regulation of asynchronous engine rotation in the non-reduction electric engine.

Low-frequency characterization of PWM converters

1985 IEEE Power Electronics Specialists Conference, 1985
Low-frequency components of states or outputs in PWM dc and ac converters can be characterized by differential equations called describing equations. These equations are derived by inspection of converter topology and use of switching functions and duty ratios.

Sakuma Frequency Converter Project

IEEE Transactions on Power Apparatus and Systems, 1965
Power system frequency has developed on a 50-cycle basis in northern Japan and on a 60-cycle basis in the south. Past efforts to unify the frequency have been unsuccessful. Both systems have now developed to the extent that this is now virtually impossible.

Solid State Frequency Converters,

1995
Abstract : New solid state static frequency converters (SSC) can be used in place of motor generator sets to produce 400-Hertz (Hz) power more efficiently. All government installations that use, repair, or build electronic components for aircraft or ships use 400-Hz power. Overall, SSCs can save 20 to 25 percent of the required input power for existing
