Series PVI
Photovoltaic Isolator
5-10 Volt Output
General Description
The PVI Photovoltaic Isolator generates an electri-
cally isolated DC voltage upon receipt of a DC input
signal. The input of the PVI is a light-emitting diode
(LED) which is optically coupled to, but electrically
isolated from, the output. A GaAIAs LED is used for
high output and maximum stability. The infrared
emission from the LED energizes, by photovoltaic
action, a series connection of silicon PN junctions. A
unique alloyed junction stack which is edge-illumi-
nated is used to form the output photovoltaic genera-
tors. This novel structure produces extremely high
operating efficiency. Units are available with a single
5-volt output or dual 5-volt outputs which can be
series connected to produce 10 volts.
A PVI can serve as an isolator, a coupler and as an
isolated voltage source. As an isolator, the PVI can
serve as the key component in a solid state relay cir-
cuits. The PVI is ideally suited for driving power MOS-
FETs and IGBTs or sensitive gate SCRs to form solid
state relays.
As a coupler, the PVI can sense a low-level DC sig-
nal and transmit a voltage signal to an electrically
remote circuit. As a voltage source, the PVI can
function as a ‘DC transformer’ by providing an
isolated, low-current DC source for biasing or
supplying power to low quiescent current electronic
devices.
Conventional optocouplers merely modulate the
resistance of an output device such as a transistor,
diode or resistor. Such optocouplers require a sepa-
rate voltage source to detect the presence of an
input signal. In contrast, a PVI actually transmits (and
transforms) energy across the isolation barrier and
directly generates an output voltage. This DC volt-
age, available at a 2500VAC isolation level, gives cir-
cuit designers a new and uniquely useful electronic
component.
