Abstract
The present invention relates to providing an electrical voltage for exciting an excitation coil of a resolver (). In this case, the electrical voltage for exciting the excitation coil of the resolver () can be generated by means of pulse-width-modulated driving of at least one half-bridge (H). In this case, the switching elements of the half-bridge (H) are fully turned on, with the result that losses such as occur during linear operation of semiconductor switches, for example, can be avoided. If appropriate, the voltage (U_e) provided by the half-bridge (H) can be additionally increased by means of suitable resonant circuits (L, C, C. . . ).
