Abstract:

This paper analysed the current waveforms in the measuring resistance concatenated with the direct current bus in the general converter. The relation between the resistance current and the load current was investigated. The system is simplified by seeking the signal processing circuit, which makes the resistance measure the load current and realize the protection in overload, overcurrent and short-circuit. The current waveforms in the practical application were presented.
