This compact IPM module circuit provides a fully-featured, high-performance inverter output stage for AC Induction, BLDC, and PMSM motors. The circuit is based on FNA23060 chip which integrates the optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features: under-voltage lockouts, over-current shutdown, temperature sensing, and […]

Although this power supply design is specific to the Intelligent Power Modules (IPM) VFD drives, high voltage boost converters, high voltage battery chargers, etc, the concept and circuit design may be used for any power supply that requires a high voltage output of up to 800V DC and 4 A. Since it is an unregulated […]

Daniel Johnson @ danielelectronics.com has build a VFD Tube Clock based on MSP430 microcontroller and explains it’s code. I wanted to do a follow-up to my last clock build, the MSP430 Analog Gauge Clock, reusing some of the code from that project, and I had an IV-18 vacuum florescent display (VFD) tube that I bought on […]
