For this reason, PSU manufacturers focus on the development of more efficient AC technologies. With the so-called "Dynamic Hybrid Transformer Topology" Enermax made the breakthrough: It is based on three pathbreaking innovations: DYNAMIC HYBRID TRANSFORMER TOPOLOGY DYNAMIC RESONANT TRANSFORMER ARRAY DYNAMIC VOLTAGE BOOSTING TRANSFORMING DYNAMIC FREQUENCIES TRANSFORMING Enermax implemented a so-called Dynamic Resonant Transformer Array. It is based on the high-efficient resonant topology which is used for example in LCD monitors. The most noticeable modification on PCB is an additional resonant choke. A RESONANT CHOKE B MAIN TRANSFORMER C DRIVER TRANSFORMER D STANDBY TRANSFORMER PSU E ciency % 91 Initially, the capacitors are charged with alternating current (AC) from the wall socket. They ensure the continuous AC supply of the transformers according to the DC consumption of the PC system.
