When using the active voltage
regulation capability of PV, the maintenance cost and the loss of power should be taken into consideration:
Therefore, the active voltage
suppression circuits, which are capable to accumulate the voltage spike energy in reactive components, have to be applied , .
The six active voltage
vectors and one zero voltage vector are utilised in the general type of ZSI inverter.
This paper focuses on the design of self-biased active voltage doubler feed by a low frequency PE transducer, as it is easily available and provides high output efficiency.
The design of the proposed self-biased active voltage doubler is presented in Section 4.
Figure 4 shows the proposed self-biased active voltage doubler circuit.
The algorithm calculation time is divided in two or three switching periods with different active voltage vectors, thus forming higher number of available voltage vectors.
Furthermore, in classical DTC, inverter's switching elements do not change their state during the whole cycle thus defining zero or one out of six active voltage vectors.
PowerSi Technologies has developedan Active Voltage
Controller that revolutionises energy conversion through the intelligent control of power semiconductor devices.
The resulting active voltage
sheet is characterized by a low impedance and high capacity to ground.
