The Tapped Inductor Switcher model of the DC-DC Converters

The steady and dynamic model of TIS blocks can be used to solve the steady-state solution of the circuit and the small signal model

This model is suitable for modeling high-gain DC-DC converters with coupled inductors. The models in the file include general three-port general model (TIS), general three-port general model with coupled inductors (ITIS), General model for high-order DC-DC converters (GTIS), general model for high-order high-gain with coupled inductors (IGTIS).And a model for DCM mode (DCM-TIS).

Each TIS model contains steady-state model and small signal model, and the steady-state model can be used to solve the steady-state solution of the DC-DC converter. The small signal model can be used to calculate the expression of the transfer function, which is convenient for the design of compensation network.

Introduction to the document:

1) : TIS model is mainly aimed at modeling low-order DC-DC converter model.

2) : ITIS model is mainly aimed at the common three-port general model with coupled inductance.

3) : GTIS model is mainly aimed at high-order DC-DC converters, such as SEPIC, CUK and Zeta models.

4) : IGTIS model is mainly aimed at the high-order high-change ratio general model with coupled inductance.

5) : DCM-TIS model is mainly aimed at DC-DC converter in DCM mode,

Operation steps:

1) : Analyze topology, deconstruct TIS components, mark port numbers, and determine voltage and current symbols and directions.

2) : Determine TIS component parameters according to the references.

3) : confirm the connection of the external linear network, establish the circuit model, and put the steady-state and small signal model into the circuit according to the port order, so as to obtain the steady-state relationship expression and dynamic characteristic transfer function equation.
