The article focuses on the coordinated control of dual pulse-width modulation (PWM) converters integrating elevator drives with energy feedback. It states that the energy difference between the rectifier and inverter per unit time can decrease if the power flow of the rectifier equals the inverter. It mentions that the direct-power control strategy is used for PWM rectifiers as the load power feed-forward method restrain the voltage fluctuation of direct current (DC) unit.
