FIRING SERIES SCRs AT MEDIUM VOLTAGE: Understanding the Topologies Ensures theOptimum Gate Drive Selection. This paper was written by Frank Peter Wahl III who is currently a design engineer with ENERPRO, Power Electronics
Control Specialists, in Goleta, CA. You can also download this paper from ENERPRO. This paper
discusses the three fundamental series SCR gate drive topologies and their most common variants, including floating bias drivers, MV pulse transformers, and light triggered designs and
compares the advantages, limitations and inherent features of each design.
GENERATED WAVEFORM MODELING And Waveform Harmonic Reduction by Filter Modeling. This paper describes how to model a nonlinear waveform generated by a
solid-state power/motor control in MathCAD. Then it demonstrates transforming this waveform from the time domain to the frequency domain using discrete Fourier transforms
providing the harmonic coefficients for the individual harmonic frequencies. Finally, it shows how to select a low pass circuit to reduce the higher order harmonics. Methods
of calculating THD of both filtered and non filtered waveforms are also shown.
MOTOR CHARACTERISTIC CURVE MODELING DURING
CURRENT LIMIT STARTING USING SOLID STATE CONTROLS And Comparison with Across The Line Starting (ATL) Methods. It describes how to model various NEMA rated motors for
both ATL and current limit starting methods for torque vs. speed and power vs. speed curves. Then it compares motor characteristic starting torque and speed for both methods.
SCR GENERATED WAVEFORM MODELING. This paper describes how to model an SCR generated waveform and calculate the RMS and average value of
current at any given delay angle. It also describes how to calculate the THD of the waveform at any given delay angle. It also shows the values of Irms, Iavg, and THD for all delay
angles from 0 to 179 degrees.
3 PHASE AC MOTOR STARTING METHODS. This paper describes basic AC induction motor circuit theory and
then discusses how AC induction motors react to both across the line starting methods and soft starting methods.
