Abstract

Conventional hysteresis current control (C-HCC) is a conventional control method with good robust and transient performance. However, due to interphase dependency, when it is used in three-phase system, high switching frequencies and current harmonics arise. This paper starts with a review of improved space vector-based HCC (ISV-HCC) reported to address the problem of conventional HCC. Then, a voltage vector-based sine-like HCC (SL-HCC) was proposed. The proposed SL-HCC refers to zero vector concept in space vector pulse width modulation (SVPWM) and sets a hysteresis band. When current errors are all within prescribed hysteresis bandwidth, zero vector switching pattern is adopted; and when current errors exceed the bandwidth, specified switching logic is adopted. Finally, by comparing with C-HCC and ISV-HCC, simulation and experiment results illustrate that SL-HCC performance is significantly improved with minimized current harmonics and lower switching frequency.
