【 摘 要 】
Rectifiers are featured by periodic processes depending on the source frequency and rectification circuit. The output current of each diode is discrete even if the load current is continuous. The relationship between the current values at the end point of the periodical working cycle of the rectifier is determined by the finite-difference method. The difference equations describing the working cycle contain constant coefficients depending on the rectification circuit type and load parameters. The analytic dependence of the current on the lattice function argument is obtained. The dependences of the current on the lattice function argument are stated for the eight-pulse rectifier with the active inductive load. The load current envelope reflects the type of the transient process and makes it possible to compare rectification circuits and to analyze steady-state processes.
