Impact of voltage subharmonics and interharmonics on currents in single-phase induction motors
In very low power drives, a single-phase induction motor is used. This motor, like the 3-phase induction squirrel-cage motor, requires a voltage supply with suitable parameters – of suitable quality, in practice.

A Method for Minimizing Subharmonics in Stator MMF of PMSM
Winding distribution plays a major role in deciding the space harmonics in the stator MMF. In this work, significance of winding layer on the MMF harmonics in surface-mounted permanent magnet synchronous motor (PMSM) with fractional slot concentrated ...

The Use of Voltage Transformers for the Measurement of Power System Subharmonics in Compliance With International Standards [PDF]
The measurement of subharmonics in distribution systems requires instrument transformers to reduce voltage and current to levels fitting with the low-voltage input of the power quality (PQ) instruments.

Influence of voltage subharmonics on induction motors of various efficiency classes
Power quality disturbances related to voltage waveform distortions and effective value deviation are common in power systems. Apart from higher harmonics, subharmonics and interharmonics may also appear in voltage waveforms.

Subharmonic functions, generalizations and separately subharmonic functions [PDF]
First, we give the definition for quasi-nearly subharmonic functions, now for general, not necessarily nonnegative functions, unlike previously. We point out that our function class incudes, among others, quasisubharmonic functions, nearly subharmonic functions (in a slightly generalized sense) and almost subharmonic functions.

SiC-MOSFET shunt active power filter based on half-cycle SDFT and repetitive control
The switching frequency of traditional active power filter (APF) is usually between 10 kHz and 20 kHz. To better suppress switching subharmonics, the output filters of APFs usually use LCL-filters.
