PRICE U$5,000 Has a new Vehicle-Based power system that has the capability of accept a variable input RPM Power source. Our Technology Raven Technology LLC has developed a breakthrough in mobile AC power. Raven's AC-DirectT technology provides 60 Hz 120 VAC power directly from a special high frequency alternator regardless of engine speed and without the costs or limitations of inverter systems. The overall system, (see diagram), is described in US Patent 6,051,959. Briefly, the output of a three-phase high frequency alternator is rectified into a single output voltage by natural commutation of diodes-devices similar to the operation of a typical automobile alternator. The output level of the alternator is controlled by modulating the field coil magnetism with a 60 Hz sine wave. This produces a 60 Hz rectified sine wave output which is then "unfolded" into a full sine wave by soft-switching as the current passes through zero. The result is a 60-Hz AC sine wave (fig 3 below) . We refer to the combination of natural commutation and soft switching as "Soft CommutationT."
