Transcript of "DC/AC Inverter (LTspice Model)"

  1. 1. DC/AC Inverter Simplified SPICE Behavioral Model All Rights Reserved Copyright (C) Bee Technologies Corporation 2010
  2. 2. Contents <ul><li>Model Overview </li></ul><ul><li>Benefit of the Model </li></ul><ul><li>Concept of the Model </li></ul><ul><li>DC/AC Specification (Example) </li></ul><ul><li>Input-Output Characteristics </li></ul><ul><li>Simulation Circuit and Setting </li></ul>All Rights Reserved Copyright (C) Bee Technologies Corporation 2010
  3. 3. 1.Model Overview <ul><li>This DC/AC Inverter Simplified SPICE Behavioral Model is for users who require the model of a Inverter as a part of their system. </li></ul><ul><li>The model focuses on the input/output relationships of the Inverter block; therefore, it is not using high frequency models (e.g. oscillator and noise models), and is not based on the electronic topologies of the Inverter. </li></ul><ul><li>The model enables long-term behavior simulation of the system (e.g. in a Photovoltaic system simulation). </li></ul>All Rights Reserved Copyright (C) Bee Technologies Corporation 2010
  4. 4. 2.Benefit of the Model <ul><li>Enable Transient Simulation. </li></ul><ul><li>Can be adjusted to your own DC/AC specifications, by editing the model parameters. </li></ul><ul><li>The simplified model is an easy-to-use, which can be provided without the circuit detail. </li></ul><ul><li>Time and costs are saved because only the necessary parts are simulated. </li></ul>All Rights Reserved Copyright (C) Bee Technologies Corporation 2010
  5. 5. 3.Concept of the Model <ul><li>The model is characterized by parameters n, Vin_min, Vin_max, Vo_ac and- Freq that represent the input-output-relationships of the Inverter. </li></ul><ul><li>Single Output DC/AC Inverter Simplified SPICE Behavioral Model </li></ul><ul><li>Efficiency (n) = P AC / P DC </li></ul><ul><ul><li> = ( Vo rms  Io rms ) / ( V IN  I IN ) </li></ul></ul>All Rights Reserved Copyright (C) Bee Technologies Corporation 2010 IN+ IN- OUT+ OUT- V IN,MIN ~V IN,MAX (Vdc) V O (V AC ) I IN I O ~ ~
  6. 6. 4.DC/AC Specification (Example) <ul><li>DC/AC Inverter with V IN =8~16Vdc, V O =100V rms , and Efficiency=80% </li></ul><ul><li>Single Output DC/AC Inverter </li></ul><ul><li>Efficiency (n) = 80% </li></ul>All Rights Reserved Copyright (C) Bee Technologies Corporation 2010 Operating Input Voltage: V IN,MIN =8 ~ V IN,MAX =16(Vdc) V O = 100(V rms ) IN+ IN- OUT+ OUT- ~
