The GaNon totem pole PFC demo board is a collaborative effort between onsemi and Future Electronics, leveraging onsemi’s NCP1681 PFC controller IC and 650-V SiC or 650-V GaN devices – with the matching driver – to provide designers with a flexible, plug-and-play environment for developing their own PFC architectures. Alternatively, it can be directly integrated into products for industrial applications, datacentres, and more.
GaNon features an 85-265 VAC input with 400 VDC output at 98.5-99% efficiency using 650-V SiC MOSFETs or GaN FETs; these measurements were taken when the board was fan cooled and powered using a 230 VAC input voltage. A 600 VDC output option is available for motor drive applications, using 900-V SiC MOSFETs. For 230 VAC input, this provides 3 kW output, and this is halved for 120 VAC input. The Total Harmonic Distortion (THD) of the design is <10%, and the Power Factor (PF) is >0.99. Variations of this highly configurable demo board are possible in consultation with the Future Electronics design team.
onsemi’s NCP1681 PFC controller IC is at the heart of the GaNon platform, and it is used to drive bridgeless totem-pole PFC topologies, which eliminate the requirement for the diode bridge present at the input of conventional PFC circuits, resulting in greatly improved system efficiency. onsemi’s controller can be configured for Continuous Conduction Mode (CCM) or multi-mode operation. Full specifications of this device can be found in this official datasheet.
GaNon is due for release in Q4 2023 with full specifications available on its release. If you are interested in using Future Electronics’ board for designing a commercial project, fill out the form below, and ipXchange will put you in touch to facilitate evaluation.
