Phase Tripler BD-3A  3-Phase Source                                     SEE VIDEO DEMO
The PhaseTripler circuit converts single-phase 60Hz AC to three-phase 60Hz AC. The single-phase source may be a function generator or the AC voltage from a step down transformer. The maximum input amplitude is 18 volts peak-to-peak. The output amplitude is the same as the input.

Phase Tripler model BD-3A is simple, easy to build, and easy to use. Its circuit board is silked screened with part numbers and is protected by a solder mask. The parts are provided on a card with labeled part numbers. It can be used as an assembly and soldering project as well as a voltage source for 3-phase experiments and demonstrations.  Available in March as a kit for $25.

 
 
 


NEW: 3PS-02  3-Phase Source                                                 SEE VIDEO DEMO

This source is simlilar to the Phase Tripler and it has the same pinout as the Phase Tripler. It has an on-board synthesized 60Hz source so that an external 60Hz input is not required. It supplies 12V peak to peak at up to 300mW per phase.

The 3PS-02 will be available in March in both assembled and kit forms.
Assembled: $55       Kit: $42

Phase Tripler II Description
 **
 

This model (BD-2A) uses the same circuit as the original Phase Tripler, except it is much smaller and uses an inline pin header which can be plugged directly into an experimenter' breadboard.   It requires a plus 12V and minus 12V DC power supply and a 60Hz single phase sine wave source.   It's output amplitude is the same as the source input amplitude up to a maximum of 18V peak-to-peak.

VIDEO DEMONSTRATION

.
Board size: 2.5 in. X 1.5 in.
Pin spacing: 0.10 in. inline
DC input: +12V and -12V

AC input: 0 to 18V p-p
60Hz, 1-phase

Output: 0 to 18V p-p
60Hz, 3-phase
  
  Note:  The 60Hz single-phase input can be from a function generator or a transformer.   
 

This is a wye-connected source with a common connection that is also the circuit ground for the power supply and op-amps. Instrument grounds cannot be connected to the output of an op-amp because that would cause a short circuit. Measurements should be made with respect to the common ground, unless the measuring instrument is known to be isolated from ground.

 The recommended maximum load current for each output is 25mA RMS. 18 volts peak-to-peak, this corresponds to about 160mW per output. The impedance of any load connected to an output should not be less than 270Ω (at 18V p-p) . Also, the very low output impedance of the op-amps contributes to excellent load regulation for load impedances of 270Ω and greater .
