PCT No. PCT/AT92/00060 Sec. 371 Date Nov. 3, 1993 Sec. 102(e) Date Nov. 3, 1993 PCT Filed Apr. 28, 1992 PCT Pub. No. WO92/20142 PCT Pub. Date Nov. 12, 1992.A method and apparatus is provided for operating a permanently excited single-phase alternating current machine, otherwise known as a transverse flux machine, which allows optimal exploitation of the machine and economical design of the converter. A terminal voltage is applied to the machine, the shape of which is defined by the characteristics of the machine. The waveform of the terminal voltage converts from a sinusoid to a square wave, with a maximum voltage equal to the maximum available voltage, at defined switch-over times. Based on the switch over times, the resulting terminal voltage wave can be square, completely sinusoidal, or a combination of both.
