ABSTRACT:
A variable duty cycle ultrasonic inverter is used to invert unregulated direct current into a high frequency variable pulse width modulated signal that is applied to a low frequency inverter by means of a high frequency transformer. The output of the low frequency is applied to an output filter where a feedback signal is coupled back to the variable duty cycle ultrasonic converter which is controlled by a comparison of the feedback signal and a sinusoidal reference signal. The sinusoidal reference signal is also used to control the low frequency inverter.
