Analysis and Optimization of the Loss Distribution for a Two
This paper presents the analysis and optimization procedure of a two-stage bidirectional AC/DC power supply. The exemplary power supply consists of a silicon carbide based active front
The switching losses are also a concern that depends on the devices and the control of the PV inverter. The length of the cables in the dc or the ac side influences the cumulative losses of LS-PVPPs. Central inverters have very high (H–H) losses at the dc side as many strings are connected in parallel.
The other losses such as switching losses and inductor conduction losses are independent of output voltage and remain constant with changes in output voltage. Hence, P now can be computed as: The other losses include the MOSFET switching losses, quiescent current losses etc.
To overcome the fault conditions, reactive power should be supplied by the PV inverter. The requirement when the voltage drops below 50% is to have an injection of reactive current of at least 100%. Thus, the PV inverter has to be oversized in the range of 1.1–1.2 to comply this requirement.
