core platform<\/strong>\u00a0(Ae = 194 mm\u00b2), purpose-built for\u00a0<strong>LLC half-bridge and full-bridge resonant converter<\/strong>\u00a0topologies operating at\u00a0<strong>60\u2013200 kHz<\/strong>. It delivers reliable galvanic isolation and efficient step-down conversion from a\u00a0<strong>380\u2013400V DC<\/strong>\u00a0bus (post-PFC) to regulated outputs of\u00a0<strong>12V, 24V, or 48V DC<\/strong>\u00a0\u2014 making it an ideal magnetic solution for\u00a0<strong>server power supplies, telecom rectifiers, EV onboard chargers, industrial DC-DC converters, and LED driver power modules<\/strong>.<\/p><p>With a nominal resonant frequency of\u00a0<strong>100 kHz<\/strong>\u00a0and a wide operating range of 60\u2013200 kHz, this transformer achieves\u00a0<strong>ZVS (Zero Voltage Switching)<\/strong>\u00a0across the load range, dramatically reducing switching losses and enabling\u00a0<strong>95%+ peak efficiency<\/strong>. The EER42 core&#8217;s cylindrical center pillar ensures uniform flux distribution and reduced winding parasitics, while the standardized bobbin platform supports rapid customization of turn ratios, pin-out layouts, and mounting styles to match your specific LLC tank parameters.<\/p><p>The design supports a\u00a0<strong>configurable turn ratio<\/strong>\u00a0(e.g., 57:17 for 400V\u2192240V, or 25:3 for 800V\u219248V) with integrated magnetizing inductance (Lm) and leakage inductance (Lr) control, enabling resonant tank design without external series inductors in many configurations. Premium\u00a0<strong>MnZn ferrite material<\/strong>\u00a0(PC40\/PC44 or equivalent) ensures low core loss and minimal temperature rise at sustained 1kW continuous operation.<\/p><h2>Applications typiques<\/h2><ul><li><strong>Server &amp; Data Center Power Supplies<\/strong><br \/>80 PLUS Titanium \/ Platinum CRPS power supplies with LLC resonant DC-DC stage \u2014 380V DC bus to 12V\/48V regulated output for server rack power delivery.<\/li><li><strong>Telecom Rectifiers &amp; Distributed Power<\/strong><br \/>48V\/50A embedded power systems and distributed power architectures requiring high-efficiency LLC resonant conversion at 1kW class.<\/li><li><strong>EV Onboard Chargers (OBC)<\/strong><br \/>6.6\u201322 kW LLC resonant converters for electric vehicle charging systems \u2014 high-voltage bus to low-voltage battery interface with reinforced isolation.<\/li><li><strong>Industrial DC-DC Converters<\/strong><br \/>High-efficiency step-down converters for industrial automation, process control, and robotics requiring reliable isolated power at 1kW class.<\/li><li><strong>LED Driver Power Supplies<\/strong><br \/>High-power LED illumination systems requiring PFC + LLC two-stage topology with high power factor and low harmonic distortion.<\/li><li><strong>Medical Power Supplies<\/strong><br \/>MOPP-compliant isolation for medical-grade power units with reinforced insulation option (2\u00d7 MOPP) per IEC 60601-1.<\/li><li><strong>Audio Amplifier Power Supplies<\/strong><br \/>Class D amplifier power supplies with low-noise LLC resonant conversion for high-fidelity audio applications.<\/li><li><strong>Syst\u00e8mes d'\u00e9nergie renouvelable<\/strong><br \/>Solar micro-inverters and energy storage DC-DC conversion stages requiring high-efficiency galvanic isolation.<\/li><\/ul><h1>Services d'ing\u00e9nierie et de personnalisation<\/h1><p>Gr\u00e2ce \u00e0 une \u00e9quipe exp\u00e9riment\u00e9e en simulation \u00e9lectromagn\u00e9tique et \u00e0 des cha\u00eenes de production conformes aux normes automobiles, nous proposons\u00a0<strong>services de prototypage rapide et de personnalisation compl\u00e8te<\/strong>\u00a0for this EER42 platform.
