Abstract
The presented paper shows an analytic way to calculate the voltages and currents in dc links of electric power trains (EPT). Using general control and signal theory the differential equation for the inductor current and dc link voltage are given. With Fourier series of the passive rectifier output voltage and the inverter input current, the equations can be solved analytically. The calculated equations are compared to a simulation in Matlab/Simulink and an experimental setup of a pump power train. The solutions can be used to generate a setpoint model for controlling the EPT or as a constraint condition in multi-objective optimized design theory.
