PMSM Motor and PWM NMOS Drive

Designer

Description

Permanent Magnet Synchronous Machine (PMSM) and PWM Drive circuit, with mechanical load. The drive includes a D-Q control algorithm, and uses space-vector modulation (SVM) to generate the digital PWM signals to drive the Power MOSFET switches of the inverter.

There are two other versions of this design. The first, "PMSM Motor And Ideal Drive", uses continuous Clarke and Park Transform models and an ideal voltage drive to represent the main features of the field-oriented control system., Another version, "PMSM Motor and PWM Drive", it similar to this version but uses ideal switches.

This version is the most detailed and therefore simulated the most slowly. It is well suited for understanding the performance of the Power MOSFETs in the context of the system, In the waveform plot on the right, the actual motor shaft angle (orange waveform) and the A-phase current (dark blue waveform) are shown. These are very similar to the results for the other two versions of the design. But the waveform plot on the left provides insight into the performance of the C-phase inverter pull-up switch. The MOSFET current Ids (green waveform), and the average power dissipated in the device (red waveform) are shown. This design can be used to size specific parts in the drive electronics, by comparing the operating conditions to which they are exposed, relative to their rated operational limits.

Description

Mekanik yük ile Daimi Mıknatıslı Senkron Makine (PMSM) ve PWM Sürücü devresi. Sürücü bir DQ kontrol algoritması içerir ve sürücünün Power MOSFET anahtarlarını çalıştırmak için dijital PWM sinyallerini üretmek için uzay-vektör modülasyonunu (SVM) kullanır.

Bu tasarımın iki versiyonu daha var. İlk "PMSM Motor Ve İdeal Sürücü", alan odaklı kontrol sisteminin ana özelliklerini temsil etmek için sürekli Clarke ve Park Transform modelleri ve ideal bir voltaj sürücüsü kullanır., Başka bir sürüm, "PMSM Motor ve PWM Sürücü", benzer bu sürüm için ideal anahtarlar kullanır.

Bu sürüm en ayrıntılı ve bu nedenle en yavaş şekilde simüle edilmiştir. Sistem bağlamında Güç MOSFET'lerinin performansını anlamak için çok uygundur, Sağdaki dalga formu grafiğinde, gerçek motor şaftı açısı (turuncu dalga formu) ve A-faz akımı (koyu mavi dalga formu) gösterilir. Bunlar, tasarımın diğer iki versiyonunun sonuçlarına çok benzer. Ancak soldaki dalga formu grafiği, C-fazlı invertör çekme anahtarının performansı hakkında fikir verir. MOSFET akım Kimlikleri (yeşil dalga formu) ve cihazda dağıtılan ortalama güç (kırmızı dalga formu) gösterilir. Bu tasarım, maruz kaldıkları çalışma koşullarını nominal çalışma sınırlarına göre karşılaştırarak sürücü elektroniğindeki belirli parçaları boyutlandırmak için kullanılabilir.

Description

This example shows a more detailed circuit- and logic-level implementation of the PID Control Loop shown in the companion example, “PID Speed Control Loop – Continuous”. The ideal motor drive block of the “Continuous” version is expanded here, to include both a H-bridge motor drive, and also the digital logic necessary for converting the continuous PID controller output into the desired PWM signals that are distributed to drive the gates of the power MOSFET switches. The MOSFET model was calibrated to represent an IRF3710, using only information published on the manufacturer’s datasheet.

The rest of the system, including the PID block-diagram controller, the mechanical fan load and the DC Motor characterized to represent an FRC CIM Motor, are the same as in the Continuous version. While the simulation time for this switching version is significantly longer, more detailed information about practical circuit performance and component sizing is available. For example, the fan speed step response is somewhat different from the conceptual design, because of the losses in the MOSFETs under high current conditions, as well as voltage drop in the battery. Also, information regarding component stress levels within the “datasheet specified” MOSFETs and Diodes is provided.
