4 FAQs about Pretoria photovoltaic cabinet bidirectional charging

How can bidirectional charging/discharging a battery achieve maximum PV power utilization?

In addition, with the proposed strategies, the bidirectional charging/discharging capability of the battery is able to achieve the maximum PV power utilization. All the proposed strategies can be realized by the digital signal processor without adding any additional circuit, component, and communication mechanism.

What is a bidirectional power directing switch?

Bidirectional Power Directing Switches The purpose of the two switches is to channel the flow of power from the panel or to the load depending on the state of the system. When the system is in the battery charging state, MOSFET Q3A is turned on and MOSFET Q3B is turned off. Power flow occurs from the panel to the battery.

What is bidirectional power flow control?

Therefore, bidirectional power flow control strategies are proposed to achieve the maximum PV power utilization as well as to realize the hybrid charging methods. In addition, with the proposed strategies, the bidirectional charging/discharging capability of the battery is able to achieve the maximum PV power utilization.

How does a bidirectional power stage work?

The bidirectional power stage operates at a 100-kHz switching frequency when working as a synchronous buck and operates at a 350-kHz switching frequency when working as a synchronous boost.
