    • Guaranteed “0”Harmonics

What is it anIntelligent Rectifier ALTIVAR 68R ?

1. Marketing advantage


Advantage intelligent rectifier altivar 68r

Recuperative braking solution (energy feedback to mains)

Input IGBT bridge

Sinusoidal current in all operating states

Mains voltage failure during brake operation leads to a controlled switching off (parameter adjustable response)

Emergency operation (parallel operation) with braking unit possible

Atv 68 r basic principle

I Diode

I IGBT

IGBT are pulsing at 5 (4) kHz

When the IGBT is on, the current flows through it

When the IGBT is switched off, the choke forces the flow of current to continue

however this time through the diode. The DC link will be overcharged during this time.

A change in the pulse/interval ratio regarding the voltage phase position influences the energy direction and the cos j

ATV 68-R – Basic principle

P = U x I

P = U x I x cosj

ATV 68-R – Start sequence

1. Start command on the Intelligent Rectifier ATV 68-R The DC capacitors are pre-charged via the pre-charging circuit All ATV 68 drives are still locked. (B3.06)

2. After the pre-charging sequence the IGBTs start to work and overcharge the DC link. The IR internal voltage control is activated. Now all ATV 68 drives (linked to the DC bus) are ready to start

Atv68r general information s for dc bus bars

Connection/disconnection of individual inverter devices to/from the DC bus is only permitted in voltage-free state.

The changed DC capacity must be notified the ATV 68-R via a digital input (see parameter group B4)

The individual inverters have to be supplied by the DC bus with super-fast semiconductor fuses. Installing these fuses to an inverter device is not allowed if the common DC bus is on voltage (this would lead to a high, short-time charging current - destruction of the device

Parallel operation of several ATV 68-R (at common DC bus) is not possible. (requires Master/Slave voltage controller structure, which is not qualified for redundant systems)

B4 dc bus data

DC-Bus capacity

The ATV 68-R operates internally with a voltage regulating structure. In order to optimize the control system, the knowledge of the whole DC capacity is required (68R + 68 values see operating instructions)By connect or disconnect power parts from the common DC bus the actual DC-capacity is changing. With two digital inputs (binary coded) this modification must be set on the Intelligent Rectifier.

C1 compensation

j

Direct default of a inductive or capacitivereactive current with the help of a selectable reference source

Load-dependent reactive current default(cos j compensation)

C1 Compensation

The IGBT pulsed line current is always in sinusoidal shape and in phase with the line voltage.So on standard settings the IR is always working on active power. (motoric and generatoric) cos j = 1

If the intelligent rectifier with the active power is not at its load limit, a phase shifter operation can be installed in addition.


C1 load dependent compensation

The load-dependent reactive current compensation should not be mistaken for a cos j compensation!

The adjustable cos j value relates to the current load of the ATV 68-R (not mains cos j )


C1 reactive current reference

The ATV 68-R can be operated as a phase shifter. With an adjustable reference source it is possible to feed an inductive or capacitive current to the line (independent from the load). The ATV 68-R works like a adjustable capacitor or choke

C1 – Reactive Current Reference

„Current management“The active current has more priority thanthe reactive. By reaching 100% apparent current the reactive current decreases automaticallyby increasing the active component fromthe load current.The overload capacity (120%) is available only for the active current.
