Variable DC-Link Voltage Regulation of Single-Phase MMC Battery …
Battery energy-storage system (BESS) based on the modular multilevel converter (MMC) can flexibly manage the battery packs integrated into submodules, where the battery pack can directly or through a small capacitor connect to the rear-end half-bridge circuit for reducing cost and volume caused by an additional dc–dc converter. But the alternating …

Question1: Option 1 is better for the following reasons: You can precisely set the cutoff voltage and you don''t depend on the manufacturing tolerance …
why the supply voltage of dc motor decreases when the motor …
Figure 1. Battery model and load. The standard method of predicting battery voltage drop is to model the battery as a perfect (constant-voltage) battery with an internal series resistance. If the battery terminals are open-circuit the voltage measured on them will be the battery voltage.
power supply
It depends. Power supplies operate on different ranges. You can check on the side of your charging cable for the specifications (usually somewhere around 100-240 Volts). If the low voltage is outside this range, it can damage the power supply and possibly the battery or laptop.

DC Power Supply System in an Electrical Substation
The battery bank provides the DC supply to load only in case the Battery charger breaks down or the AC supply to the battery charger breaks down. So in normal conditions, it is the charger that supplies DC power to protection, communication, control, and measurement devices running in the Electrical substation & not the battery bank.
How to Obtain Negative Voltage from a DC Power Supply or Battery
DC Power Supply. Let''s begin with the DC power supply. So a DC power supply normally has 3 terminals: +, GND, and -. The + is the positive terminal of the voltage supply. The - is the negative terminal of the DC voltage supply. And ground is earth ground. The earth ground can connect to either nothing (left floating), the + terminal or the ...
