Applications

• The DPC circuit targets several applications mostly related to sensing & power conditioning
• Power conversion: DC-DC, AC-DC, DC-AC and AC-AC converters
• Motor control: DC, stepper motors & AC up to 6 phase motors
• Intelligent remote sensor: one example of such function is decentralized control of sensors
• Distributed bus client in power conditioning
• Data bus protocol translation (gateway): aggregation & concentration of connections to several clients and interface through e.g. standard mil-1553B or CAN buses.
