Two-phased SVPWM based on H-bridged structure

In this paper, a novel space-voltage vector pulse width modulation (SVPWM) is presented based on H-bridged driving circuit. By the method the problem that there is no zero space vector to meet frequency restraint condition in 2-phased SVPWM is solved. The control principle and the definition of para...

Description
Summary:In this paper, a novel space-voltage vector pulse width modulation (SVPWM) is presented based on H-bridged driving circuit. By the method the problem that there is no zero space vector to meet frequency restraint condition in 2-phased SVPWM is solved. The control principle and the definition of parameters are introduced through the topology of power circuit of 2-phased H-bridged structure. At last, the SVPWM method is utilized to control the 2-phased hybrid stepping motor, and experimental results indicate that the double closed-loop control system with 2-phased SVPWM method has a better dynamic characteristics and steady-state performance.
