The IPS1 board is fed by a +24 Vdc ±10 % power supply. This supply must have a minimum capacity of 4 Adc.
3.4.7 Input Filter
This section presents the types of filter, define criteria for their choice depending on the application and
specify values and characteristics of components used in these filters.
3.4.7.1 Basic Definitions
The proper operation of the regenerative converter demands the use of a three-phase reactance between
the input and the power supply. This three-phase reactance is known as LBOOST (boost reactor). In most
cases, it is used an additional LC filter between the LBOOST and the power supply in order to eliminate
the high frequency currents flow generated by the IGBTs switching to the power supply. In this manual, the
components connected between the power supply and the regenerative converter are identified as filters.
