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.

Abstract: An emergency power system is connected between an AC voltage source and a load. The emergency power system ensures a stable voltage on the output, even if the AC voltage received from the AC voltage source is irregular or is interrupted briefly. The emergency power system includes an AC/DC converter coupled between the load terminals and an AC regulator positioned between the AC voltage source and the load. The AC/DC converter is coupled to a chargeable battery and serves as a charging rectifier for the battery in normal operation and as an inverter in emergency operation, the battery voltage being converted to AC voltage on the output of the emergency power system. The AC regulator is built as a controllable current generator supplying on its output an AC current which is in phase with the AC voltage received from the AC voltage source. Irrespective of the energy direction through it, the AC/DC converter maintains the predetermined AC voltage (V.sub.OUT) across the output terminals of the emergency power system. The system includes a comparator which senses and compares the battery state to a predetermined reference and supplies a signal in response to this. The intensity of the current supplied by the AC regulator is controlled in response to the signal generated by the comparator so that in terms of energy the system is in power balance.
