Simulation of RISC processor control based power converter circuit and system

This paper describes a new simulation approach for a RISC processor controlled series-parallel resonant high frequency DC-DC power conversion system. All the control algorithms are implemented in software. Software of control algorithms in the simulation program is also applicable in a RISC processor control based system. This power electronic circuit simulation technique is based on a circuit equation modelled by substituting switch modulated resistors in place of all the active and passive power switches incorporated in the power converter circuit, one state-vector equation described by state-variables for inductors and capacitors, and an algebraic computation method to transform the matrices of the circuit equation into matrices of the state vector equation
