6 FAQs about [Energy storage emc rectification]

How much space does a synchronous rectifier save?

The latter is a space savings of 53 mm2. Both designs use the same LC filter and a 750-kHz switching frequency. Figure 3 shows the efficiency and power loss of both designs with a 12-V input and a 15-V output. The ideal duty cycle is 20%. The ben-efit of the synchronous rectifier is clear in this example.

How does a synchronous rectifier work?

With a synchronous rectifier, there are two main sources of power dissipation—conduction and dead-time loss. When the low-side switch turns off, there is a time delay (tDELAY) before the high-side switch turns on. During this delay, the body diode (VSD) of the high-side switch con-ducts current. Typically this is referred to as dead time.

Besides, energy storage systems are also introduced in distributed systems to stabilize the power output of renewable energy [22, 23]. The power electronic conversion system is the interface to connect the energy storage system with the power grid.

Does a synchronous rectifier improve power efficiency?

The ben-efit of the synchronous rectifier is clear in this example.
