Abstract
The invention relates to a switch mode power amplifier. A first and a second change-over switch are inserted between a DC voltage supply and a primary side of an isolation transformer. Two secondary windings are connected to a power output terminal. A first and a second secondary side power switch are adapted to connect the two secondary windings to the power connector of the power output terminal. The pulse width modulation means is adapted to generate control signals for the driver means of the first and the second change-over switch so as to cause every second pulse to be inverted. The pulse width modulation means is also adapted to generate a third and a fourth control signal for said driver means of the power switches of said first and said second secondary. The invention also relates to a method of controlling a switch mode power amplifier
