  • Circuit assembly having a transformer with centre tapping and measuring of the output voltage
    Patent number: 10379142
    Abstract: To enable in a circuit arrangement (8) with a transformer with center tap the voltage measurement on the secondary side simply and safely, it is provided that at least two series-connected resistors (R3, R4) are connected between the two outer connections (A1, A2) of the secondary side of the transformer (T) to form a measurement point (P) between the two resistors (R3, R4), and a voltage measurement unit (V) is provided to measure the voltage (UP) between the measurement point (P) and the second output pole (13), which corresponds to the output voltage (UA).
    Type: Grant
    Filed: March 1, 2016
    Date of Patent: August 13, 2019
    Assignee: FRONIUS INTERNATIONAL GMBH

  • Resonant converter having a transformer with central point tap
    Patent number: 10199941
    Abstract: In order to set the output voltage of a resonant converter to a desired value by means of a simple additional circuit while the resonant converter is in open circuit operation, it is intended that at least one capacitor each (C1, C2) is connected in parallel to the electrical switching elements (S1, S2) of the secondary side of the resonant converter (1).
