Main Contributions and Interests
- Characteristics and applications of the staircase waveform produced by DAC are being investigated, some manuscripts have been published.
- A new concept of Non-Integer-Period Sampling of ADC and a new compensation algorithm to overcome the leakage errors.
- An idea to use an electrical compensation approach to replace the mechanical one (spike, nosepiece) for better adjusting fineness and more perfect result.
- In charge of a project to builthe national primary standard of capacitance (calculable capacitor).
In charge of a project to build and finish the national primary standards of the three phase power/energy, and of the harmonic power at industrial frequency.
