“…Based on the simplified model are derived formulas for the standard method of compensation, which are frequently used in different variants, for example in the (Haifeng & Yuyao, 2014;Sam-Young Kim et al, 2010). Unfortunately, this model contains several simplifications and neglect of some phenomena, such as charging and discharging of the parasitic capacitance.…”

“…This algorithm can be used only for vector-controlled PMSM drives in which current control loop is employed. The voltage distortion estimator for a vector controlled PMSM driver are presented in (Haifeng & Yuyao, 2014; Sam-Young Kim, Wootaik Lee, Min-Sik Rho, & Seung- Yub Park, 2010). The compensation voltages in the rotor reference frame are derived online by development a simplified model of PMSM due to much slower dynamic response of rotor than electro-magnet.…”

“…The method is based on monitoring the variation of the current slope developed by the nonlinearity of VSI. The compensation method using the integrator output of the synchronous d-axis proportional-integral (PI) current regulator is proposed in (Hwang, Seon-Hwan, 2010 Park, 2010). The compensation voltages in the rotor reference frame are derived online by development a simplified model of PMSM due to much slower dynamic response of rotor than electro-magnet.…”

Effective Dead-Time Compensation Using Adaptive Harmonic Compensator

This paper aims at analyzing and compensating the dead-time effects in the vector-controlled AC system. The use of dead-time in power electronics drive systems to prevent a short circuit in the DC link is necessary. However, dead-time can lead to distortion of VSI output voltage and ripple of phase current. It is used a feed-forward approach for the standard compensation and a feedback loop with adaptive harmonic compensator to suppress the persistent sixth harmonic components in dq-currents. This proposed approach is validated by simulation and real experiment.

The load torque disturbance influences the performance of permanent magnet synchronous motor speed control. Therefore, to compensate this problem, this paper designed a model reference torque observer based on Popovsuper-stability theory. This observer uses off-line calculation to obtain the model parameters and PI calculation of the speed model error to get the load torque. This structure is simple and easy to implement for speed control compensation. The compare of this observer and a reduced order torque observer is studied by simulation. The results show that the model reference observer designed this paper has better performance in convergence, noise immunity and observation accuracy, and is more suitable for speed control compensation.

High dynamic and low output distortion are the key requirements of power converters in high‐precision motion control. The soft‐switching auxiliary resonant snubber inverter (ARSI) has the advantage of low dead‐time effect is very suitable to be used in high‐precision applications. However, the auxiliary switches in ARSI suffer from over‐voltage problem due to the resonance between the junction capacitors of auxiliary switches and resonant inductor. Besides, all switches of natural zero‐voltage switching (‘NZVS+NZVS’ mode) under the light load condition brings about voltage error. Thus, the clamped auxiliary resonant snubber converter (CARSC) is proposed in this paper. Extra diodes are added, which can not only reduce the voltage stress of auxiliary switches but also save the freewheeling energy for the next commutation to improve the efficiency. Moreover, all switches of auxiliary zero‐voltage switching (‘AZVS+AZVS’ mode) is proposed to reduce the voltage error of ‘NZVS+NZVS’. The experimental results demonstrate that the over‐voltage problem is addressed and the loss of the proposed CARSC is reduced. Besides, the high‐precision performance of CARSC is verified. The lowest THD of the output current is 0.015%. © 2022 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.
