This document describes a simplified SPICE behavioral model for a 3-phase DC/AC inverter. The model allows for transient simulation of the inverter's input-output characteristics without detailed circuitry. It is parameterized based on the inverter's specifications, such as voltage and efficiency ratings. Simulation examples are provided to demonstrate the inverter's output voltage, current, efficiency, and behavior at minimum input voltage.
This chapter discusses principles of steady-state analysis of DC-DC power converters. It introduces inductor volt-second balance and capacitor charge balance, which relate the average inductor voltage and capacitor current to be zero during steady-state. A small ripple approximation is used to simplify analysis by ignoring output voltage ripple. Examples of steady-state analysis of the buck and boost converters are presented using these principles to determine output voltage, inductor current, and capacitor sizing for given ripple levels.

This document provides an overview of a tutorial on integrated circuit design of power management circuits. The tutorial covers topics such as switching converters, including fundamentals and control techniques; bandgap references; charge pumps; and low dropout regulators. It lists these topics along with brief descriptions in an agenda. It then begins discussing switching converters in more detail, covering concepts such as steady state analysis, lossless elements, buck, boost and buck-boost converter topologies, volt-second balance, continuous and discontinuous conduction modes, and efficiency calculations.
