“…It is only feasible to attenuate the harmonics by adding a filter to the main circuit. However, this increases the cost and size of the whole circuit [10]- [12]. Judging by the simulation results, improving the switching frequency by using the optimal current source space vector control will cause certain grid-side current distortions.…”

This paper analyses the harmonic pollution to power grids caused by several high-power rectifiers, summarizes the requirements for rectifiers in suppressing grid-side current harmonics and optimizes a new-type of current source PWM rectifier with a hybrid switch. The rectifier with a hybrid switch boasts significant current characteristics and cost advantages in the high-power area. To further enhance the working frequency of the current source rectifier with a hybrid switch for suppressing grid-side harmonics and reducing the inductance size, this paper proposes an optimal control strategy based on space vector. It also verifies that the optimal control strategy based on space vector can reduce the total harmonic distortion of the grid-side current of the rectifier with a hybrid switch via circuit simulation and experimental results.

Energy production has continuously now become center of attraction as the global energy problem has become more significant. The Pulse Width Modulation (PWM) inverter's creation and application are critical to renewable energy technologies. Furthermore, one of the most essential concerns for PWM Inverters is Over Modulation (OM) performance. OM technology improves the primary voltage and current, reduces device variable reaction time, & increases the normal operating zone.The harmonic current issue, the difficulty of the overmodulation approach, and the seamless transition between linear and overmodulation areas are all emphasised as important issues with the overmodulation strategy.The merits and downsides of common overmodulation methods are contrasted and explained in this paper.
