Latest Patents

Hoang Van Hung holds a patent for an "Apparatus and method for compensating output signals of magnetic encoder using digital phase-locked loop." This invention includes a pre-calibration unit, an advanced phase detector, a loop filter, a voltage-controlled oscillator (VCO), and a pulse generator. The pre-calibration unit is designed to obtain two phase-compensated waveforms through trigonometric function operations. It adjusts the amplitudes of these waveforms to the same value, generating input sine and cosine waves. The advanced phase detector generates an error output signal through trigonometric function operations, while the loop filter sets the filter transfer function of an active lead-lag filter to filter the error output signal. The VCO generates a compensated signal, and the pulse generator outputs a phase index, producing two output pulses with a 90-degree phase difference according to a pulse generation rule from a look-up table.
