DC-AC Inverter Circuit Description

Example of Circuit using Discrete Solution

Circuit Description

Signal line in DC-AC inverter circuit requires isolation from the power line. Optical coupling type photocouplers can be used for simple and reliable isolation. We recommend an IC output photocouplers that have capable of high-speed communication. In addition, it is essential to comply with the safety standards set by each country. Toshiba Photocouplers have been approved by UL1577, VDEs:EN60747-5-5, EN62368-1 and others. The output stage also contributes to lower power consumption due to MOSFET of low on-resistance and higher output due to transistor arrays with high withstand voltage and large current.

Examples of typical recommended products are listed below, and also provide a link to the online distributor inventory search page to buy the product.

Recommended Products (Isolators/Solid State Relays)

Our isolators/solid state relays offer a lineup of photocouplers, solid-state relays (SSRs), and optical transmission modules. Photocouplers contribute greatly to improving the safety of equipment, reducing power consumption, and making them smaller and thinner.
