400Hz inverters for air-borne radios
This text presents the requirements and possible solutions for the task of providing 400Hz AC power to aircraft radios. Part 1 covers introduction and data of commercial units and explores and documents an experiment using a "simple" PWM inverter. The results are usable but not really satisfactory and part 2 will describe a more complex solution using today's technology. Unfortunately that part is still in the works, sorry.
