Abstract

The invention relates to a resonant converter ( 200, 300 ). The resonant converter ( 200, 300 ) consists of a first circuit, primarily a DC circuit ( 201, 301 ) connected to a resonant circuit ( 207, 307 ) which is further connected to a switch/filter circuit ( 212, 312 ) which is connected to a second circuit, primarily an AC circuit ( 219, 319 ). The proposed resonant converter ( 200, 300 ) is unique in that the resonant converter ( 200, 300 ) contains a direct connection between a voltage center ( 203, 303 ) in the DC circuit ( 201, 301 ) and a voltage center ( 209, 309, 325 ) in the resonant circuit ( 207, 307 ), and that the resonant circuit ( 207, 307 ) contains at least one transformer having at least two windings ( 223, 224, 331, 332, 333, 334 ), wherein there is a connection from the windings ( 223, 224, 331, 332 ) of the transformer to at least first and second switches ( 215, 216, 315, 316, 328, 329 ), wherein activation of the switches ( 215, 216, 315, 316, 328, 329 ) forms a connection to at least a first node ( 214, 314, 327 ), wherein a voltage center ( 203, 303 ) in the DC circuit ( 201, 301 ) is also connected to the first node ( 214, 314, 327 ) by activation of at least a third switch ( 213, 313, 326 ). This results in a resonant converter ( 200, 300 ) wherein there are just switches ( 213, 215, 216, 313, 315, 316, 326, 328, 329 ) in the switch/filter circuit ( 212, 312 ) so that the number of switches ( 213, 215, 216, 313, 315, 316, 326, 328, 329 ) with power loss is as low as possible. The resonant converter ( 200, 300 ) moreover has the advantage that there is a direct connection from the center ( 203, 303 ) of the DC circuit ( 201, 301 ) to the load ( 219, 319 ), without this current path running through the coil ( 217, 317, 330 ) to the resonant circuit ( 207, 307 ). This minimizes the current load of the coil ( 217, 317, 330 ) and hereby the influence on the frequency of the resonant converter in case of a short-circuit on the output of the resonant converter ( 200, 300 ) where a great output current is to be provided, while the output voltage is close to zero volt. The reason is that a switch ( 213, 313, 326 ) in the switch/filter circuit ( 212, 312 ), which is connected to a voltage center ( 214, 314, 327 ), will conduct for by far the greatest part of the time at an output voltage close to zero volt, and that this current path bypasses the resonant circuit ( 207, 307 ). In addition, reduced switching across the switches ( 213, 215, 216, 313, 315, 316, 326, 328, 329 ) is achieved.
