Abstract (en)
[origin: WO2004055961A2] The invention relates to a resonance converter for driving variable loads, wherein an input signal which is supplied by a switch (103) which is controlled by a control device (109) is initially converted into an output signal by a transformer (105). The dimensions and circuitry of the transformer (105) are such that the transformation ratio between the input signal and output signal ranges from 1.5:1 to 5:1 when nominal power is supplied to the variable load (107). The switching frequency of the switch (103) is controlled on the basis of phase displacement between the switch current and the load current for a modifiable load and/or variable input voltage. The inventive resonance converter enables variable loads to be driven efficiently with the aid of a transformer.
