摘要： A resonant DC/DC converter for supplying an output power comprises a switching device (18) for supplying a switched voltage (UWR) to a resonant circuit (20) having a transformer (T). The switched voltage (UWR) is derived from an intermediate circuit voltage (Uz) having a fixed pulse width and frequency so that the zero crossings of the resonant current (Ires) generated in the resonant current are defined. The switching configuration of an inverter circuit (18) is selected by a control device (31) to either increase, decrease or maintain at a substantially constant level the resonant current according to the polarity of the switched voltage, so as to control the output power as required.

摘要： In the case of known switched-mode power supplies with integrated preconditioner, the control curves are largely congruent, but deviate from one another in low-load operation, whereby the unregulated intermediate circuit voltage increases. To improve efficiency in low-load operation, closed-loop control of the burst cycle is effected on the primary side of the voltage transformer. The intermediate circuit voltage (Uic) is limited to a permissible limit value (U limit). The closed-loop control device in the switching stage taps the intermediate circuit voltage at a voltage divider (R1, R2) which is arranged between the preconditioner functional unit (12) and the switching stage (13). An assembly additionally monitors the output voltage, for example by means of an optocoupler (17). Burst mode comprises one or more burst cycles. A burst cycle is started when the intermediate circuit voltage (Uic) reaches its limit value (U limit). At this time, the voltage transformer is switched off. A burst cycle ends when the output voltage (U0) reaches a minimum value (U min). At this time (t3) at the latest, the voltage transformer (7) is switched on again. Burst mode is terminated again either when the switched-mode power supply is again operated under normal load or when a maximum time has elapsed, measured from the start of burst mode.

摘要： A power supply power supply (30) comprising a DC voltage supply, a control unit and a plurality of high voltage channels (33a- 33d) is suggested. Each high voltage channel (33) includes an inverter (IKTV) , a resonance circuit, a transformer (TR) , and a rectifier (RECT) . The resonance circuit cooperates with the inverter (INV) . The inverter (INV) is formed by a first switching unit and a second switching unit whereby a voltage of a first polarity can be applied to the resonance circuit in a first switching state, whereas a voltage of a second polarity can be applied to the resonance circuit in a second switching state. The switching states can be switched by the control unit in such a manner that in a first mode of an operation for high output power, the output power can be adjusted by changing the switching frequency in the range of the resonance frequency. In a second mode of operation for low output power, the output power can be adjusted by changing the duration of the switching state at an essentially constant switching frequency.
