The information of three-phase currents are very important for motor control. Some three-phase current reconstruction techniques were used in conventional two-level inverters using single DC current sensor for the purpose of cost reduction and sensor

This paper proposes a new soft switching bi-directional DC-DC converter. The described converter employs the symmetric topology with high frequency transformer. It gets soft switching with the designed pulse-width modulation control, which guarantees

High rate of variation of common-mode voltage (CMV) brings problems to the pulse width modulation (PWM) inverter motor drive system. In this paper, a new two-stage CMV reduction PWM strategy is proposed. In the high voltage region, the peak-to-peak v

In this paper, a novel zero voltage switching (ZVS) bi-directional DC/DC converter is presented. With the specially designed control strategy, the symmetric converter achieves the soft switching for all the switches include the diodes. Thus, it reduc

This paper presents a new solution, which can completely remove the DC offset and compensate the steady-state error for voltage model flux estimation in an induction motor (IM) direct torque control (DTC) system. The voltage model flux estimator has

A new soft switching bi-directional DC/DC converter, which can achieve ZVS for all switches in large load range, is introduced in this paper. Besides, the diode reverse recovery is also diminished with zero current switching (ZCS). These measures red
