active rectification造句

Replacing a diode with an actively controlled switching element such as a MOSFET is the heart of active rectification.
However, all switching regulator topologies can be made bidirectional and able to move power in either direction by replacing all diodes with independently controlled active rectification.
The control circuitry for active rectification usually uses comparators to sense the voltage of the input AC and open the transistors at the correct times to allow current to flow in the correct direction.
Using active rectification to implement AC / DC conversion allows a design to undergo further improvements ( with more complexity ) to achieve an active power factor correction, which forces the current waveform of the AC source to follow the voltage waveform, eliminating reactive currents and allowing the total system to achieve greater efficiency.
It's difficult to find active rectification in a sentence. 用active rectification造句挺难的
