PCB transformer
Application Scenarios
High-frequency power supply: GAN fast charging (100kHz+ switching frequency), industrial DC-DC module.
Communication equipment: Network transformer signal isolation (4kV insulation).
Automotive electronics: Space-sensitive scenarios for OBC onboard chargers.
Core product features
Technical Performance
- The operating frequency is extended to 50Hz-2MHz, compatible with both industrial frequency and high frequency scenarios;
- Leakage inductance is controlled within 0.5% of the primary inductance, and efficiency is increased to over 92%;
Structural advantages
- Height is compressed to 1/3 of the traditional transformer (typical value is 5mm), and the power density reaches 30W/cm³;
- The core and PCB are encapsulated with epoxy resin, reducing vibration noise by 15dB;
reliability
- Insulation resistance >100MΩ under 500VDC test, and 1500VAC withstand voltage meets safety standards;
- Temperature rise ≤50K at 40℃ ambient temperature, supporting -40℃~125℃ operating range.
Typical application scenarios
Industrial power modules
The DC-DC conversion unit used in PLC control cabinets solves the heat dissipation and space conflicts of traditional EI transformers in compact chassis.
medical devices
The medical ultrasound probe power isolation module uses its low magnetic leakage characteristics to avoid interference with sensitive signals.
New energy field
The boost circuit of the photovoltaic micro-inverter is adapted to the requirements of the high-frequency MPPT algorithm.
