Power Converter With Amplitude Control Facility

Power Converter with Amplitude Control Facility is used for controlling heater loads that previously required a transformer. 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.

Key features of Power Converter with Amplitude Control Facility are as follows:
# Protective operation when power supply operated under high resistive loads[flicker]
# Operation of low voltage heaters directly at the power supply without impedance-matching transformer
# Minimum harmonics in the instrument power supply and low weight [power transformer n/a]
# Short-circuit control when switching on
# Line current in proportion to the required power [amplitude control]
# Control independent of the heaters` resistive characteristics
# Minimum reactive power with compact dimensions
