Customer ServiceAbstract: This paper proposes a harmonic compensation method using an open-ended winding IPMSM driven by an electrolytic capacitor-less dual inverter in a motor drive system. In the conventional electrolytic capacitor-less single inverter, harmonics caused by the DC-link voltage ripple frequency are superimposed on the motor phase current under a distorted input voltage.
Customer ServiceThe controller, after some calculations, decides on the capacitor stages closest to these powers and activates them. However, after the capacitors are switched on/off, unlike conventional capacitor switched compensation systems, the reactive powers drawn from each phase of the grid must be of the same type.
Conventional switched capacitor compensators are the most commonly used structures for reactive power compensation of distribution network loads. These structures offer an energy-efficient and cost-effective solution for reactive power compensation.
The circuit diagram of compensation capacitors and peripheral hardware in the implemented hybrid reactive power compensation system is also given in Fig. 7. As can be seen in this figure, there are six single-phase and two three-phase capacitors. Rated powers of each capacitor are also shown in the same figure.
We may infer from Figure 2 that the DC link capacitor’s AC ripple current Icap arises from two main contributors: (1) the incoming current from the energy source and (2) the current drawn by the inverter. Capacitors cannot pass DC current; thus, DC current only flows from the source to the inverter, bypassing the capacitor.
For three-phase inverters at any DC bus voltage, for films and electrolytics, respectively, a rule of thumb is that about 5 and 50 millicoulombs of capacitor nameplate CV rating will be required per amp of ripple current.
As can be seen in this figure, there are six single-phase and two three-phase capacitors. Rated powers of each capacitor are also shown in the same figure. In the hybrid system, as a controller, a program that was written in accordance with the method explained in the previous section was used.
