12. ANNEX

12.1 DEFINITIONS OF TECHNICAL TERMS

DC/DC booster Switching technology for increasing a DC voltage to
a higher voltage level
Device protection Term from the field of overvoltage technology
Conventional mains overvoltage protection consists of
a lightning arrester (class B), overvoltage protection
(class C), and what is referred to as the device
protection (class D)
IGBT Insulated Gate Bipolar Transistor
High-performance, state-of-the-art transistors with
an ultra-low control power requirement (MOSFET
structure) and ultra-low losses on the output side
(structure of a bipolar transistor)
Class D See device protection
LED Light Emitting Diode
Electronic semiconductor component used for optical
signaling
PFC Power Factor Correction
Switching technology for minimizing circuit feedback
(especially important when connecting non-linear
loads)
PWM Pulse-Width Modulation
In this case: switching technology for generating a
maximum-quality sinusoidal voltage from an existing
DC voltage
SNMP Simple Network Management Protocol
Common protocol in the network for managing
components
VFD Output Voltage and Frequency Dependent from mains
supply. The UPS output is dependent on mains
voltage and frequency fluctuations. Previously called:
OFFLINE
