| Abstract |
In order to determine which small signal model most accurately describes PWM converters, a comparison with a switched model is necessary. Due to parasitic effects the comparison with hardware measurements does not clar-ify this question. Therefore published small signal models based on ideal components are compared with a time do-main simulation of a switched converter using the same idealization in this paper. The transfer function is deter-mined by emulating the quadrature detector used in practi-cal measurement set-ups. The paper shows the theoretical background, the implementation in SPICE and the com-parison with traditionally found transfer functions. |
