In a second sub-mode ('low output power sub-mode'), VOUT is regulated using pulse width modulation, but the converter switching frequency is fixed at a first frequency.
In this paper, a current control mathematical model is established with fixed switching frequency for three-phase pulse width modulated (PWM) converter.

Double space vector modulation and overmodulation of matrix converter were proposed in this paper to ensure the matrix converter switching frequency to be fixed and fast dynam-ic torque response.
