Power Tool and eBike Battery Chargers

Power Tool IconeBikes

With the growing demand for eco-friendly transportation, electric bicycles (eBikes) are becoming increasingly popular. Certain countries have even passed laws to encourage the adoption of eBikes. For example, China has decided to stop issuing new licenses for gas powered bicycles and now only issues licenses for eBikes. Many of these new laws also set weight requirements for lighter bikes, creating the need for smaller batteries and highly efficient chargers. To meet this need, PI offers charger solutions featuring its broad range of highly integrated, high-voltage ICs.

    Power Tools

    Power Integrations offers a broad range of highly integrated, high-voltage ICs for off-line power conversion in power tools applications. Solutions include flyback, two-switch forward, and LLC topologies from 5 to 586 W output power. Each device combines high voltage MOSFETs, a controller, and protection circuitry in the same heat-sinkable package. Accurate constant current (CC) control provides reliable designs that meet the requirements of power tool battery charger applications.

    Design features include:

    • Current limiting and thermal shutdown (with automatic fault recovery capability) to improve reliability
    • Frequency jittering to reduce EMI
    • High switching frequency significantly reduces the magnetic size
