Photovoltaic isolators

PVI - Isolator for solar panels

anchor

Overview

Our photovoltaic isolators (PVI) offer single- and dual-channel, optically isolated outputs that can be used for directly driving the gates of discrete power MOSFETs and/or IGBTs. This range of devices gives designers the flexibility to create custom solid-state relays capable of controlling loads in excess of 1000 V and 100 A.

Key Features

  • Low-power consumption
  • Do not generate electric arcs
  • Stable contact resistance
  • Positional insensitive

Introduction of the photovoltaic isolators

The PVI series photo-voltaic isolators employ fast turn-off circuitry. No power supply is needed on the output side, unlike conventional MOSFET or IGBT drivers. The dual-channel PVI can drive independent discrete power MOSFETs or provide a higher voltage drive for IGBTs.

Details of photovoltaic isolators

 The PVI utilizes a monolithic integrated circuit photovoltaic generator as its output. The output is controlled by radiation from a GaAlAs light-emitting diode (LED), which is optically isolated from the photovoltaic generator. The PVI series is ideally suited for applications requiring high-current and/or high-voltage switching with optical isolation between the low-level driving circuitry and high-energy or high-voltage load circuits. It can be used for directly driving the gates of power MOSFETs. The dual-channel PVI can drive independent discrete power MOSFETs or higher voltage drives for IGBTs. The PVI series photovoltaic isolators employ fast turn-off circuitry. No power supply is needed on the output side, unlike conventional MOSFET or IGBT drivers.

Key Features

The photovoltaic isolator's important key features, e.g., 1 Form A (single channel, normally open) and 2 Form A (dual channel normally open), the integrated fast turn-off circuitry, compact solutions that are available in DIP8 and SMT8 packages, input to output isolation of up to 4 kV rms, 1200 V(DC) output to output isolation in dual channel version, dual-channel configuration which allows its outputs to drive independent discrete power MOSFETs, or be connected in parallel or in series to provide higher-current drive for power MOSFETs or higher-voltage drive for IGBTs and no power supply is needed on output side.
