JUMO IPC
IGBT Power Converter
with amplitude control
Brief description
The JUMO IPC is a power converter for controlling heater loads that previously required a
transformer (either a variable transformer or a combination of transformer and thyristor
power converter).
Its function is that of an electronic transformer with a pulsed DC output.
It combines the advantages of a conventional variable transformer, such as amplitude
control which is the sinusoidal current loading, with the advantages of a thyristor power
switch, such as current limiting, load monitoring, subordinate control action, etc.
There is no electrical isolation between the supply voltage and the load voltage.
This power converter is employed wherever substantial resistive loads need to be
switched.
To operate the IPC, a choke and a line filter are indispensable in addition to the IPC power
converter itself. Only the chokes or line filters specified by JUMO may be used for this pur-
pose. Thanks to the amplitude control (the current drawn from the supply is always sinu-
soidal), synchronous clock controls (as for burst-firing operation) and power-factor
compensation networks (for the reactive power resulting from phase-control) are no longer
required.
