摘要

This paper proposes a new topology for an AC/AC converter without DC energy storage to compensate deep voltage sags and swells and to control the output voltage phase shift. The analyzed topology is based on an AC/AC CukB2 bipolar matrix-reactance chopper. The proposed solution is intended to protect sensitive loads and energy flow control in the AC power grid. The main advantage of the proposed solution is the combination of the properties of a series AC voltage compensator and phase shifters without DC energy storage. The presented AC/AC voltage converter is able to compensate single phase voltage interrupts, three-phase up to 50% voltage sags and swells, and change the phase of output voltage simultaneously and independently in relation to the input voltage. The paper presents an operational description, theoretical analysis and the experimental test results from a 1 kVA laboratory model using a PWM control strategy with open feedback loop.
