How the drive system works to reduce the drive system and DC link current ripple

摘要

Systems and methods are disclosed for operating a drive system that is coupleable to one or more DC and AC electrical ports. Such a drive system comprises at least one DC-DC converter and at least one relative to each other based on a DC link, at least one DC-DC converter, at least one DC-AC converter, a DC link capacitor, and its operating parameters. A control system configured to control the operation of one or more of the DC-AC converters. In controlling the operation of at least one of the at least one DC-DC converter and the at least one DC-AC converter, the control system is adapted to control the switching frequency of the at least one DC-DC converter, the switching frequency of the at least one DC-AC converter, DC-. Control at least one of the DC converter carrier signal phase, the DC-AC converter carrier signal phase, and the duty cycle of the at least one DC-DC converter.
