This document describes Variable Speed High Frequency Alternators for diesel engine driven gen-sets with variable speeds in range from 600 RPM to 3,600 RPM and HF Alternator for gas turbine engine driven gen-sets with variable speeds in range from 8,700 RPM to 60,000 RPM. This document describes also two-step and single-step Powe Frequency Converters for conversion of high frequency AC power to NIL-STD frequency and voltage (such as 60 Hz and 120 VAC). Described converters utilize power transistors or SCR devices. Power transistor based Pulse Width Modulation (PWM) Power Frequency Conversion Technology is suitable for 5-60 kW gen-sets while converters based on SCR devices ("Cycloconverter") can be used for all power ranges. Described Variable Speed High Frequency Alternators and Power Frequency Converters can be used in the following power ranges: 5-30 kW, 30-100 kW, and 100-1,000 kW.
