Current-Fed Topology: Robust Power Conversion All MagnaDC programmable DC power supplies utilize high-frequency IGBT-based power processing in current-fed topology. This topology adds an additional stage over the conventional voltage-fed topology for enhanced control and system protection, ensuring that even under a fault condition, the power supply will self-protect. Due to the self-protecting characteristics of this topology, the possibility of fast rising current spikes and magnetic core saturation is eliminated. In addition to its robust topology, key performance characteristics of MagnaDC programmable DC power supplies include: High-accuracy voltage and current programming accuracy Class-leading line and load regulation performance High 3F AC input power factor with in-rush limiting circuitry Computer and user I/O isolated from the power supply output For more details, read: Current-Fed Power Processing—Ride Through Robustness
