The Trip to Town; power with the truck or sedan Question: Ok, . . our critical load requirements combined exceed a single inverter capacity, can you explain alternative architectures? Answer: Diversify the application by using smaller load bundles and deploy inverters with either INTERLACED or DISTRIBUTED architectures. These Alternative Architectures naturally build fault-tolerance and resilience into your application network. Application Engineer's Discussion: This is a typical a...
Hybrid Power Architectures using Mixed Sources for Fault-Tolerant Applications Many utility installations already contain Energy Storage Systems (ESS) for maintaining continuous operation during times when a grid supply is not available to the location. For our hybrid systems discussion, consider the ESS being a 130v direct-current (dc) source. A converter power system is used to transform dc at 130V to 48V dc in the shelf system and support the individual protection circuits. The rectifier p...
Dual Power Systems in a Diversity Array for Fault-Tolerant Applications As the power shelf systems are paired to provide an additional fault-tolerant level of dc power support, additional diversity is realized. In this array, there are two power shelf systems each with multiple protective devices linked to load apparatus. Dual power arrays will double the control and telemetry from an installation, as both systems contain communication ports. Each system will operate independently to tr...
Single Power System for Fault-Tolerant Applications The simple configuration employs a power shelf and two or more circuit protection devices, for example fuses or circuit breakers. A single power shelf system can support many A/B loads when the current requirements are low and the adequate protection devices are installed. Alternating-current (ac) diversity is managed through individual power module cord connections. Consideration given to each source of the “mains” connection can i...
