Realisation of a high-speed drive using a BLDC motor, especially that of low and medium power and with rotational speed of up to 40 000 rpm designed for use in aviation appliances, became possible due to rapid progress in electronic power control technology. An increase of both capability and diversity of electronic power circuits results from the increase of semiconductor element voltage and current operational ranges simultaneously with the improvement of their dynamical parameters, as well as from application of up-to-date microprocessor and programmable circuits for control purposes. Choice of topology for a drive system to be used in aviation appliances, including the electronic power converter, is based on the following quality and economy-related criteria: single-phase supply and sinusoidal waveform of power network current; high efficiency and reliability; small overall dimensions; minimum number of semiconductor elements; and low price. Various technical solutions are possible here, concerning both the scope of the power circuit and the control system.
