OLD MAID. SPINSTER. CHILDLESS CAT LADY. For literally centuries now, everyone from gossipmongers to vice presidential candidates has slung dismissive sobriquets to describe the single woman experience ...

Chip maker Qualcomm Qualcomm has announced its planning to acquire Arduino, a company that makes open source hardware & software including single-board microcontroller kits. The QQRB2210 processor ...

Enphase Energy, a California-based provider of solar inverters and energy storage systems, launched its IQ9N-3P, a three-phase microinverter for commercial-scale solar projects. The microinverter is ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small boards ...

Abstract: This paper presents a Field Programmable Gate Array (FPGA) implementation for rapid prototyping of a new single-phase transformerless five-level inverter for PV applications. The inverter ...

I build robots that move, blink, and sometimes even creep you out. From animatronics to 3D printing experiments, I fuse mechanics, electronics, and creativity to bring ideas to life. Follow to see ...

The single-phase inverter series can take between 4.5 kW and 12 kW of PV input and convert it to an AC output of 3 kW to 8 kW. The new products feature a maximum efficiency of 97.6%. Chinese ...

Deye said its new single-phase off-grid inverters have an AC output power ranging from 3.6 kW to 6 kW. The systems feature a maximum efficiency of 97.6% and a European efficiency rate of 96.5%.

A transformerless PV inverter has no galvanic isolation between the input and the output, leading to current leakage problems. Parasitic capacitance plays a crucial role in the circulation of leakage ...
