Abstract:
1. A power modulator comprising: a plurality of switched pulse generator sections; a power supply arrangement connected to inputs of said plurality of switched pulse generator sections for supplying power thereto; a transformer arrangement, a primary side of which being connected to outputs of said plurality of switched pulse generator sections; said transformer arrangement having an output connected to a secondary side of said transformer arrangement; a switch control, being connected to said plurality of switched pulse generator sections for providing control signals for at least one of turning on and turning off said plurality of switched pulse generator sections; said switch control being arranged to provide control signals for at least one of turning on and turning off switched pulse generator sections of a first subset of said plurality of switched pulse generator sections at a first time instant and to provide control signals for at least one of turning on and turning off switched pulse generator sections of a second subset of said plurality of switched pulse generator sections at a second time instant, different from said first time instant, said second subset being different from said first subset.
