Abstract Diabetes mellitus (DM) is a serious chronic metabolic disease that can lead to many complications, such as cardiovascular disease, retinopathy, neuropathy, and kidney disease. Once diagnosed with diabetes, patients need take oral hypoglycemic drugs or use insulin control blood sugar slow down the progression of This has significant impact on daily life patients, requiring constant monitoring side effects medication. It also imposes heavy financial burden individuals, their families,...

Fault ride-through (FRT) control and protection are of vital importance for a modular multilevel converter-based high-voltage direct current (MMC-HVDC) system when dc-side pole-to-pole (PTP) or pole-to-ground (PTG) fault occurs. In this paper, FRT strategy by reversing dc voltage polarity is proposed symmetrical bipolar full-bridge submodule-based MMC-HVDC system. It suitable both PTP PTG faults. By adopting method, the stress in scenario eliminated. Meanwhile, capability transmitting rated...
