3.1 What Is an Electronic Load
When measuring the characteristics of the power supply in designing a power sup-
ply, a load that is applied to the power supply is required. An electronic load refers
to a device that uses semiconductors (transistors) in place of a variable resistor to act
as a load. Because voltage and current can be controlled freely on a semiconductor,
the load can be controlled arbitrarily by embedding a control circuit.
The electronic load is used as (1) a load for various electronic circuits, (2) a load for
characteristics tests and life tests of various DC power supplies such as a switching
power supply and primary and secondary batteries, and (3) a load for aging. The
sequence function can be used to simulate the load tests of power supplies with
large load fluctuation (such as a power supply for a printer) in a condition that is
close to the actual load.
