Abstract In power electronics, Predictive Current control (PCC) and Predictive Torque control (PTC) methods are advanced control strategy. To control an induction machine (IM), the Predictive Torque control (PTC) method evaluates the stator flux and electromagnetic torque in the cost function and Predictive Current control (PCC) (Cortes et al., 2008) considers the errors between the current reference and the measured current in the cost function. The switching vector selected for the use in IGBTs minimizes the error between the references and the predicted values. The system constraints can be easily included (Burtscher and Geyer, 2013; Geyer, 2013). The weighting factor is not necessary. The PCC and PTC method with 15-level H-bridge inverter using IM reduce 19% more THD in torque, speed, and stator current compared to the PTC and PCC methods with 2-level voltage source inverter compared to Wang et al. (2015). In this paper, switching losses minimization technique through THD minimization. Switching losses are minimized because the transistors are only switched when it is needed to keep torque and flux within their bounds. The switching pattern of semiconductor switches used to get better performance of multilevel inverter. This scheme decreases the switching loss and also increases the efficiency. In this paper, the PTC and PCC methods with 15-level H-bridge inverter using IM are carried out and gives excellent torque and flux responses, robust, and stable operation achieved compared to the PTC and PCC methods with 2-level voltage source inverter compared to Wang et al. (2015). This novel method attracted the researchers very quickly due to its straightforward algorithm and good performances both in steady and transient states (Wang et al., 2014).

具有 15 电平逆变器的模型预测直接转矩控制驱动器的 PCC 和 PTC 方法的开关损耗最小化和性能改进

摘要 在电力电子中，预测电流控制（PCC）和预测转矩控制（PTC）方法是先进的控制策略。为了控制感应电机 (IM)，预测转矩控制 (PTC) 方法评估成本函数中的定子磁通和电磁转矩，预测电流控制 (PCC)（Cortes 等人，2008 年）考虑电流参考之间的误差以及成本函数中的测量电流。选择用于 IGBT 的开关矢量最大限度地减少了参考值和预测值之间的误差。系统约束可以轻松包含在内（Burtscher 和 Geyer，2013 年；Geyer，2013 年）。加权因子不是必需的。使用 IM 的 15 电平 H 桥逆变器的 PCC 和 PTC 方法在扭矩、速度、与采用 2 电平电压源逆变器的 PTC 和 PCC 方法相比，定子电流和定子电流与 Wang 等人相比。(2015)。在本文中，开关损耗最小化技术通过 THD 最小化。开关损耗被最小化，因为晶体管仅在需要将扭矩和磁通保持在其范围内时才进行开关。半导体开关的开关模式用于获得更好的多电平逆变器性能。该方案降低了开关损耗并提高了效率。在本文中，与使用 2 电平电压源逆变器的 PTC 和 PCC 方法相比，使用 IM 的 15 电平 H 桥逆变器进行了 PTC 和 PCC 方法，并提供了出色的转矩和磁通响应、稳健和稳定的运行与王等人相比。(2015)。
