摘要： A pulse-width-modulated inverter models the output response of the system for a given switching angle set under existent load and d.c. link conditions. Before implementation, a provisionally selected angle set is input to the model, which produces an output representative of system operation for the provisional selected set. The harmonics content of the model output is compared with criteria establishing maximally allowable amplitudes for the harmonics and the set is implemented only if the output meets the criteria.

摘要： An inverter controller adjusts a selected switching pattern to accommodate minor variations and loads in the neighborhood of that pattern. The controller realizes in real-time the equivalent of an iterative solution of predetermined patterns. A number of representative pulse width modulated (PWM) patterns are selected for a range of loads and link ripple. A portion of the fundamental output is inserted onto the d.c. link to control one or more higher harmonics.

摘要： This invention relates to a VSCF system for aircraft power generation having a DC source, the DC source producing a substantially constant voltage DC signal. An inverter is coupled to the DC source and receives the DC signal, applying a PWM pattern of switching transients to the DC signal to produce an AC signal from the DC signal. The subject invention contemplates the addition of a feedback circuit which comprises a transformer providing an inductive coupling between the AC signal at a point of regulation and the DC signal at a point between the DC source and the inverter to eliminate short duration switching transients in the PWM pattern. Modulation of the DC signal allows short duration switching transients in the PWM pattern to be lengthened, thereby avoiding physical minimum time switching limitations in the switches of the inverter. Feedback of the AC signal allows inverter frequency to be changed while maintaining synchronization between the DC signal modulation and PWM pattern fed to the inverter.
