N2 - A four quadrant HF AC Chopper is described, analyzed and verified experimentally. The main advantage of the proposed topology is the ability to handle reactive loads without the need for a deadtime between switches. This is accomplished by dynamically configuring the chopper as positive or negative Buck or Backward Boost converters corresponding to the momentary polarities of the input voltage and output filter inductor current. A 300W breadboard unit was built to test the proposed concept. The experimental results conform to the expected behavior of proposed chopper.
