Abstract: A method for providing grid-forming control of an inverter-based resource includes monitoring the electrical grid for one or more grid events. The method also includes controlling, via a power regulator of a controller, an active power of the inverter-based resource based on whether the one or more grid events is indicative of a severe grid event. In particular, when the one or more grid events are below a severe grid event threshold, thereby indicating the one or more grid events is not a severe grid event, the method includes controlling, via the power regulator, the active power according to a normal operating mode. Further, when the one or more grid events exceed the severe grid event threshold, thereby indicating the one or more grid events is a severe grid event, the method includes controlling, via the power regulator, the active power according to a modified operating mode.

Abstract: A blower assembly for a powered air-purifying respirator (PAPR) assembly includes: a lower housing; an upper housing connected to the lower housing, such that the upper housing and the lower housing collectively define a first interior cavity; a filter configured to filter ambient air drawn into the blower assembly; and a fan. The upper housing and the filter define a pathway for a flow of air into the first interior cavity. The fan is positioned in the first interior cavity such that, when the fan is activated, ambient air is drawn into the blower assembly and travels along the pathway into the first interior cavity for subsequent delivery out of the blower assembly. The lower housing defines an outlet port for directing breathable air out of the blower assembly for delivery to a user (e.g., via a breathing tube interconnecting a headpiece and the outlet port).

After the control over the transmission coupling is completed, the torque of the second motor is controlled so that the output torque of the output shaft follows a predetermined target torque while the torque of the first motor is controlled to be increased.
