Base station 48v inverter voltage regulation

What is a 48V 12Kw inverter of BSG?

A 48V 12kW inverter of BSG was designed with paralleled TO-Leadless MOSFETs. The phase current was up to 500Arms while the VDS voltage spike was under 70V. The maximum temperature rise of MOSFET was 30°C, and the current of MOSFET was balanced well. This design fulfilled the power requirement with 105°C liquid cooling system.

How do grid-forming inverters achieve power support and voltage optimization?

This paper proposes a robust voltage control strategy for grid-forming (GFM) inverters in distribution networks to achieve power support and voltage optimization. Specifically, the GFM control approach primarily consists of a power synchronization loop, a voltage feedforward loop, and a current control loop.

Do PV inverters participate in the Volt/VAR control?

In this case, only conventional devices participate in the Volt/Var control. The control is purely based on local measurements (Short, 2004). The LTC and VR control settings are highlighted in Table 1. Table 1. Set points for legacy devices. Even though PV inverters are shown in Figure 4 they do not participate in the Volt/Var control.

How a GFM inverter is controlled?

The GFM inverter is controlled as a voltage source, which achieves control objectives by generating the output voltage amplitude and phase reference. The structure of the control module primarily consists of power control and voltage control.
