One of possible modulated load voltage and current shapes measured on the load (Only low frequency multiple-modulated signals are presented)

Modulated load current and voltage shapes measured on the converter: Upper: Modulated Voltage and Current signals in low frequency domain Lower: Carrier Voltage and Current ultrasonic frequency signals (Complex modulation of the carrier signal is not visible)

An example of modulating feedback signals

Movable, floating and sweeping spectrum of the load current
