Abstract

The low power factor is a main shortcoming of the common cascade control system at all times. A digital trigger and the related main circuit of a new three-phase four-wire cascade control system in the paper can raise the power factor of the system. This paper discusses the work principle of the system and the rule of generating the trigger pulses, and mainly introduces the trigger hardware of the new three-phase four-wire cascade control system taking ADuC812 as the key component and corresponding software
