Desain dan Implementasi Inverter Satu Fasa 400 Watt dengan Metode Switching High Frequency

“…3 (1), 2019, pp. [9][10][11][12][13][14][15][16] Inverter merupakan perangkat elektronika yang dipergunakan untuk mengkonversi tegangan Direct Current (DC) menjadi tegangan Alternatting Current (AC). Keluaran suatu inverter dapat berupa tegangan AC dengan bentuk gelombang sinusoidal murni, gelombang kotak, dan sinusoidal modifikasi.…”

Coupled physics solvers for analysing the magneto‐thermal behaviour of a permanent magnet synchronous machines

“…The two-dimensional magnetic field formulation of calculation is based on magnetodynamic Maxwell's equations, which leads the following partial differential equation [1]: The electric machine can be analysed as a two-dimensional problem if we assume that the physical behaviour of the machine is the same in axial direction.…”

“…The core loss of electric machine with sinusoidal excitation is commonly computed based on loss separation, which 2 of 2 Section 7: Coupled problems breaks the total core loss into static hysteresis loss, classic eddy-current loss and excess loss components [1][2][3]: The source terms, J s and H c are the z-component of the source current density and the coercive field strength of the permanent magnet.…”

“…In the developed model, total losses including winding loss and iron loss are simulated in Maxwell, ANSYS software. The core loss of electric machine with sinusoidal excitation is commonly computed based on loss separation, which Section 7: Coupled problems breaks the total core loss into static hysteresis loss, classic eddy-current loss and excess loss components [1][2][3]:…”

Review of the Analytical Flow Model to Predict the Hydraulic Behaviour in Electrical Machine

“…The airflow speed in the different sections of a throughventilated machine can be calculated by two different methods: analytical flow network analysis and numerical computational fluid dynamic (CFD) [4]. The hydraulic circuit method is the 1D analytical method which models the various flow paths of the machine [5]. This method is the fast calculation method with acceptable accuracy [4].…”
