摘要:
This paper proposes a constant hysteresis -band current controller with lower fixed switching frequency by adding zero mode control at proper time. An extra k-band is introduced for creating a degree of freedom to achieve constant switching frequency and maintain fixed hysteresis -band simultaneously. Detailed theoretical basis of the proposed fixed switching frequency hysteresis current controller is then presented in the context. Existence condition of the proposed control is also derived. Finally, a simplified hardware system is constructed to verify the validity of the proposed control.
