Purpose

The purpose of this paper is to develop a novel coupled analysis method for synchronous rectification alternators.

Design/methodology/approach

An ideal diode module is embedded in a rectification circuit. The resistance of the diode module is set such that it is equal to the on-resistance of the MOS-FET modules in the generation mode. In a mode without power generation, the motor voltage is less than the bus voltage; a sufficiently large value is defined for simulating the infinite resistance.

Findings

Because there is no need to decide the switch timing in advance, only one round of coupled analysis is needed to evaluate the synchronous rectification alternators.

Research limitations/implications

As limited case study is denoted in this paper, much more case studies are needed to be discussed.

Practical implications

By using the proposed method, it can be fulfilled that generation characteristic of automotive alternators can be evaluated without using the control simulation or pre-conducted analysis to decide the switch timing.

Social implications

By using the proposed method, it can be fulfilled that generation characteristic of automotive alternators can be evaluated without using the control simulation or pre-conducted analysis to decide the switch timing.

Originality/value

In the proposed methods, the definition of diode module differs from that of a conventional coupled analysis.
