Research
- Broadband RF power converter
Overcoming the inherent limitations of narrowband and linear amplifiers, broadband switched-mode RF power conversion enables high-efficiency operation with flexible control and fast dynamic response. This capability benefits a wide range of applications, including medical imaging, plasma generation, induction heating, and wireless power transfer.
- Dynamic impedance transformation network
Almost no real-world application presents a constant load to power converters, posing a fundamental challenge to robust and efficient operation. Advanced impedance transformation techniques enable rapid matching under fast-changing load conditions, maintaining high efficiency and stable power conversion.
- Efficient gate drive
Resonant gate drives enable high-power operation at high frequencies for large transistors by recycling gate energy, reducing drive loss, and supporting fast, efficient switching.
- High voltage DC-DC power conversion
Various applications, such as ion pumps and X-ray generation, rely on compact high-voltage supplies in the kilovolt range with ultra-low ripple and strong galvanic isolation.
