A resonant transformer is one that has a capacitor connected to one or both of its windings, acting as a tuned circuit. Resonant transformers can serve as high Q factor bandpass filters when used at radio frequencies. Resonant transformers are frequently employed in switching power supply and bandpass filters in radio circuits.
Sine wave in its purest form. power factor during testing of unity. Safe procedure because voltage reduces if the specimen fails. Low input voltage serves the objective due to large voltage amplification.
The Global resonant transformer market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
For inductor-inductor-capacitor (LLC) applications, Vishay Intertechnology has unveiled a novel resonant transformer that combines an integrated inductor with the transformer in a single package.
The 5.5 kW Vishay Custom Magnetics MRTI5R5EZ features completely controllable magnetising and leakage inductance with minimum parasitic variation. It is designed to conserve PCB space while streamlining layouts and lowering component mounting requirements.
Onboard chargers, half-bridge and full-bridge resonant power supply transformers, solar inverters, industrial controls, military, avionics, and construction equipment will all employ the MRTI5R5EZ.
The transformer’s losses can be transferred from the core to the coil as necessary to produce the greatest performance and heat dissipation, and its minimum parasitic variation improves capacitor selection. It also offers an adjustable turns ratio for various applications.
The device operates between 100 and 350 kHz, has a rated power of 4 to 6 kW, an input voltage range of 400 to 800 V, and a rated current of up to 28 A. The MRTI5R5EZ is rated for an isolation voltage of 2500 V. The transformer comes with a cold-plate mounting bracket with raised bosses and various flush-mount alternatives.
