What is a capacitive compensation battery?
The capacitive compensation battery is obviously connected on the low voltage (LV) side during an opencircuit test of the transformer rated at 110 or 220 kV. For this purpose, the battery should be capable of a voltage of 6–22 kV equal to the voltage of the transformer primary winding.
What is the relative power of a capacitive compensation battery?
The relative power of the capacitive compensation battery in the SC tests, conversely, is higher with a higher transformer power. The relative power of the capacitive compensation battery is 0.66% for the 125MVA transformer and already 0.79% for the 625MVA transformer.
Does a single capacitor compensate a volt-ampere?
In early studies, single capacitor compensation is adopted in IPT systems . However, this compensation method fails to provide enough design freedom to juggle the volt-ampere rating of the power supply and good output characteristic . Thus, it has been phased out and replaced by a double-sided compensation network.
What is a compensation circuit?
The compensation circuit plays a crucial role in the framework of Capacitive Power Transfer (CPT) in wireless Electric Vehicle (EV) charging schemes. Various wireless charging factors such as power transfer capacity, efficiency, and frequency depend on the design of compensation circuit topology.
