Recent advances in loss minimization algorithms for IPMSM drives

Power losses Analysis in Frequency Domain of IPMSM Drive fed by Cascaded H-Bridges Multilevel Inverter

“…The main drawback is correlated to the pulse-width-modulated voltage waveforms that generate high-frequency harmonics on both voltage and currents, causing significant additional power losses with respect to sinusoidal supply, which reduces motor efficiency, producing noise, vibrations and heat [3]- [4]. In this scenario, industrial and academic researchers pushed their efforts towards the optimization of electric drives performances by reducing the motor power losses both with hardware and software solutions [5]- [8]. Furthermore, the standardization bodies have recently released various standards [9]- [10] concerning power losses measurements of electrical drives and by defining the energy efficiency indicators for Power Drive Systems (PDSs), Complete Drive Modules (CDMs) and motors.…”

Characterization of the parameters of interior permanent magnet synchronous motors for a loss model algorithm

“…A relevant branch of these strategies is represented by the Loss Model Algorithms (LMAs), which consider the power losses minimization of the motor by choosing the appropriate level of magnetization in order to maximize its efficiency for different working conditions. The most diffused losses minimization approaches presented in the literature [1][2][3][4][5][6][7] can be classified in two main categories: the Search Control (SC) and the Loss Model Control (LMC). The first strategy consists of a step-by-step change of a control variable and a real-time measurement of the active power of the motor.…”

Analysis and Design Considerations of an Electric Vehicle Powertrain regarding Energy Efficiency and Magnetic Field Exposure

“…Esta idea fue aplicada por primera vez en máquinas de inducción para resolver el mismo problema: optimizar la eficiencia energética mediante la determinación empírica del flujo óptimo [105,106]. Posteriormente la propuesta fue trasladada a máquinas síncronas de imanes permanentes [107,108] e incluso a máquinas síncronas de reluctancia [109], pero desde que se desarrolló el control MTPA parece que ha perdido interés y ha pasado a un segundo plano.…”
