The V/Hz speed controller conjoined with the sinusoidal PWM (SPWM
) technique constitutes the control algorithm of the PWM inverter as exposed in Fig.

technique for 3-0 VSI using STM32F4 discovery board interfaced with MATLAB," in 2016 IEEE 7th Power India International Conference (PIICON), Bikaner, India, November 2016.
This paper presents the implementation and comparison of bus-clamping strategy over SPWM
The adjusted values of ([delta], M, ...) will compose the reference signal as the input of the SPWM
block (called 3-phase generator with SBC).
What is worse, the duty ratio in each switching cycle is changing and cannot calculate them as SPWM
using modulation function.
Many PWM control methods have been proposed for ZSI by far, including simple SPWM
, maximum SPWM
, maximum constant boost control , and modified SVPWM (MSVPWM) [11, 12].
Then, the triggering pulses on the inverter switches are gained by sinusoidal pulse-width modulation (SPWM
Q1 and Q2 are alternately commutated through SPWM
modulation; this produces a linear circuit for each time subinterval, as illustrated in Fig.
Currently, tests for working memory include the n-back task  which is a continuous performance task commonly used to measure a part of working memory , the Sternberg Item Recognition Paradigm [11,12], the Visual Patterns Test , the Spatial Working Memory task (SPWM
) , and others [15-18].
