Patent DE-19700740-A1 (DE)
Title: Frequency evaluation method for sinusoidal signal section
Inventor: SCHEIDIG HARDY DIPL ING
IPC: G01R23/02
Filed: 1997-01-11
Abstract: The frequency evaluation method uses a Hilbert transformer for providing a pair of orthogonal signals from the received sinusoidal signal section, with calculation of the actual phase using the arctan of the quotient of the orthogonal signals.  The frequency is evaluated from the gradient of the phase function obtained by linear regression. The sinusoidal signal section may be converted into an input signal for the Hilbert transformer via an A/D converter.

Abstract: The invention relates to a d.c.-d.c. converter with a transformer and a reactance coil. The inventive d.c.-d.c. converter also has a controllable switch (S1) for switching the direct supply voltage (UB) on and off. The contact gap of a switching transistor (S1) is connected to reference potential on the connection tap between the primary winding (L2p) and the secondary winding (L2s) of the reactance coil (2), which is transformer-coupled with a set transformation ratio (u). The anode-cathode gap of a diode (D1) and an output capacitor (C2) is connected to reference potential in series with the secondary winding (L2s) of the reactance coil, the output voltage (UA) for a load (RL) being applied through the output capacitor. The input direct voltage is conveyed to the primary winding of the reactance coil via an inductor (L1) and a capacitor (C1) is located parallel to the contact gap of the switching transistor, said inductor (L1) and said capacitor (C1) creating a series resonant circuit which is effective in the switch-on and switch-off phase of the switching transistor.
