While operating under the same laws of physics and using the same materials (i.e. copper, ferrites) like the conventional transformers, these Planetics® planar transformers have different construction geometry that reflects handful of technological advantages. The small size and weight of Planetics® enable the designer to minimize the SMPS physical dimensions. The excellent repeatability, high efficiency (97-99%) and efficient cooling methods have already made Payton's Planetics® the preferred technological choice in many of the world leading electric companies. This commercialized innovative technology is available at competitive prices compared with conventional technology, while introducing all these advantages for a power range of 10W-10000W in one unit, operating in 50kHz-2.5MHz, for all SMPS topologies. This technology complies with all safety standards and is UL approved. Summary of Benefits Advantages Comments High Power Density Up to 3 times compared to conventional transformers High Current Capability Up to 200A per winding layer Large Power Capacity 5W - 20,000W in a single unit High Efficiency Typically 98% without a volume increase Good Thermal Conduction Short thermal path, lower temperature rise Good Heat Dissipation By attaching to chassis or heat sink Low Profile Suitable for modern applications Low Leakage Inductance About 0.2% of primary inductance High Parameter Repeatability Fixed, pre-tooled winding structure Low EMI Emission Efficient core shielding Large Operating Frequency Range From about 20 kHz to more than 1MHz Availability Available as samples and in production quantities at competitive price levels
