A Current mode Three-phase Space Vector Signal Technique Based on Analog Method

This paper presents a technique for generating analog current-mode 3-phase space vector signals in the weak inversion region of the MOS transistor to optimize the modulation by the SVPWM method. The proposed circuit is designed using a half-wave rectifier and an amplifier circuit structured as MOS transistors. PSpice simulates the performance and applications of the proposed circuit at ±0.7V supply voltage, which has a maximum power consumption of 3.21uW. The simulation results correspond to the theory. The SVPWM method can solve the overmodulation problem.
