fi elds, which are transmitted through the air.  EMI refers to 
electrical currents, which are conducted in wiring connected 
to the device.

The Vyper

 generates both  RFI and  EMI. Most  RFI energy 

generated by Vyper

 is contained within it’s cabinet. The  EMI 

energy is conducted back in to the power line, and may be 
capable of causing interference to other electronic equipment 
that is powered  by the same electrical distribution system.

VSDs are used successfully in many installations, which uti-
lize sensitive electronic equipment. However, in some highly 
sensitive cases, there may be electronic equipment that is 
affected by Vyper

 originated  EMI. For those cases, an op-

tional  Harmonic Filter is recommended to reduce conducted 
 EMI levels by reducing current harmonics to limits defi ned by 
the IEEE 519-1992 standard. The fi lter is located within the 
Vyper

 cabinet and is factory installed and tested. The fi lter 

can also be retrofi tted to an existing Vyper

.

The IEEE 519 fi lter is required on all hospital applications, and 
is strongly recommended for any installation with sensitive 
electronic equipment connected to the electrical distribution 
system. The fi lter is also required whenever a local utility 
places a limit on current distortion for an electronic device.  
The IEEE 519 harmonic fi lter is fi lter is required where total 
harmonic current distortion must be 8% or less.

SYSTEM OPERATING CONDITIONS

Refrigeration systems considered for Vyper

 application 

must be in good operating condition. A site survey should be 
completed with the help of a trained Frick service technician.   
The technician will review the condition of the equipment and 
recommend actions that must be taken to ensure that the 
equipment is in good operating condition. This survey must 
be taken and required repairs made prior to the application 
of the Vyper

.

PNEUMATIC CONTROLS

 Pneumatic controls must be replaced with  electronic controls 
to be compatible with the Vyper

 and the Quantum LX

 

control panel.

VYPER

 SYSTEM OVERVIEW

The Frick Vyper

 Variable Speed Drive is a  liquid-cooled, 

transistorized,  PWM inverter in a highly integrated package. 
This unit is factory designed to mount either remotely on a 
stand or integrally to the compressor package. The power 
section of the drive is composed of four major blocks: 

•  AC to DC rectifi er section with integrated  precharge circuit

•  DC link fi lter section

•  Three-phase DC to AC inverter section 

•  Output suppression network

An electronic circuit breaker with  ground fault sensing con-
nects the AC line to an  AC line choke and then to the DC 
converter. The line choke will limit the amount of fault current 
so that the electronic circuit breaker is suffi cient for protecting 
the Vyper

 input fuses. (See schematic, Figure 8) 

THE AC TO DC SEMI-CONVERTER

 uses 3 Silicon Con-

trolled Rectifi ers (SCRs) and 3  diodes. One  SCR and one 
diode are contained in each module. Three modules are 
required to covert the three-phase input AC voltage to DC 
voltage (1SCR-3SCR). The modules are mounted on a liquid-

cooled heatsink. The use of the SCRs in the semiconverter 
confi guration permits precharge of the DC fi lter link capacitors 
when the chiller enters the prelube cycle. It also provides fast 
disconnect from the AC line. The  SCR trigger board provides 
the turn on and turn off commands for the SCRs. The Vyper

 

logic board provides commands to the  SCR trigger board 
during precharge.

THE DC LINK FILTER SECTION

 of the drive consists of a 

series of  electrolytic fi lter capacitors (C1-C6). These capaci-
tors provide a large energy reservoir for use by the DC to 
AC inverter section of the Vyper

. The capacitors are con-

tained in the Vyper

 Power Unit. “Bleeder” resistors (RES1 

and RES2) are mounted on the side of the Power Unit to 
provide a discharge of the DC Link fi lter capacitors after 
power is removed.

THE DC TO AC INVERTER SECTION

 of Vyper

 serves 

to convert the DC voltage back to AC voltage at the proper 
magnitude and frequency as commanded by the Logic 
board. The inverter section is composed of one power unit. 
This power unit is composed of very fast switching transis-
tors known as an  Insulated Gate Bipolar Transistor (IGBT) 
module (1MOD) mounted on the same liquid-cooled  heatsink 
as the semiconverter modules, the DC Link fi lter capacitors 
(C1-C6), a semiconverter, and a Vyper

 Gate Driver board. 

This board provides the turn on, and turn off commands 
to the IGBT’s output transistors. The Vyper

 Compressor 

Drive Logic board determines when the turn on, and turn off 
commands should occur. The gate driver board is mounted 
directly on top of the IGBT module, and it is held in place with 
mounting screws and soldered to the module. This improves 
reliability by eliminating the gate wires and their possible 
failure. In order to minimize the parasitic inductance between 
the IGBT module and the capacitor bank, copper plates which 
electrically connect the capacitors to one another and the 
IGBT modules are connected together using a “laminated 
bus” structure. This “laminated bus” structure forms a  parasitic 
capacitor which acts as a low valued capacitor, effectively 
canceling the parasitic conductance of the copper plates. To 
further cancel parasitic inductances, a series of small fi lm 
capacitors (C7-C9) are connected between the positive and 
negative plates at the IGBT module.

THE VYPER

 OUTPUT SUPPRESSION NETWORK

 is 

composed of a series of capacitors (C10-C12) and resistors 
(3RES-8RES). The job of the suppressor network is to reduce 
the time it takes for the output voltage to switch as seen by 
the motor. It also limits the peak voltage applied to the mo-
tor windings, as well as the rate of change of motor voltage. 
These are  problems commonly associated with PWM motor 
drives such as stator winding end turn failures and electrical 
fl uting of motor bearings.

Other sensors and boards are used to convey information 
back to the Vyper

 and provide safe operation of the variable 

speed drive. The IGBT transistor module contains a thermis-
tor  temperature sensor that provides temperature information 
back to the logic board via the gate driver board. The AC to 
DC semiconverter heat sink temperature is also monitored 
using a thermistor temperature sensor (RT2). The uses the 
three resistors on the board to provide a safe impedance 
between the DC link fi lter capacitors located on the power 
unit and the logic board. This provides the means to sense 
the positive, midpoint, and negative voltage connection points 
of the VSD’s DC Link. Three current transformers (3T-5T) 
monitor the output current from the Vyper

 power unit and 

are used to protect the motor from over-current situations.
