Undervoltage and overvoltage protection
Web12 Jul 2024 · \$\begingroup\$ When you are building an undervoltage lockout circuit, you need to give it some hysteresis. When the undervoltage protection kicks in, the battery gets disconnected and stops supplying power to the boost converter. This causes the battery voltage to rise slightly and the undervoltage circuit will no longer detect an udervoltage … Web22 May 2024 · Undervoltage and overvoltage protection. The bus-connected overvoltage relay is a time-delayed relay and is set to trip the bank if the system voltage exceeds the total voltage rating of the bank and before the unit voltage withstand time is exceeded.
