“…Inductance L s is used for the simultaneous fine-tuning of the frequencies f o1 and f o2 and for the reactance -j/ωC x to frequency sensitivity setting (in case the impedance Z x is capacitive). The signal corresponding to the frequency difference between the frequency f o1 and reference frequency f r or difference between the frequency f o2 and reference frequency f r enters the LP (Low Pass) (which is a pulse wide modulated signal [33][34][35]). With the help of the reference frequency f r , both signals f o1 and f o2 (4 MHz) are converted to the range between 2−100 kHz, which is suitable for the further signal processing.…”

A new high sensitivity temperature-compensated reactanceto-frequency transducer with two quartz crystals oscillating in the switching oscillating circuit is presented. The novelty of this method lies in the switching-mode converter bringing a considerable reduction of the temperature influence of AT-cut crystal (the crystal's x axis is inclined by 35°15' from the z (optic) axis) frequency change in the temperature range between 10−50 °C and in the use of additionally connected sensing reactance in parallel to the shunt capacitances of the two quartzes. The oscillator switching method and parallel switching reactances connected to the quartz crystals do not only compensate crystals' natural temperature characteristics but also any other influences on the crystals such as ageing of both the crystals and other oscillating circuit elements. In addition, the method also improves reactance-to-frequency sensitivity, linearity and reduces the output frequency measurement error. The experimental results show that through high temperature compensation improvement of the quartz crystals' characteristics, this switching method theoretically enables a 100 zF resolution. It converts capacitance in the range 4−8 pF to frequency in the range 2−100 kHz.

“…Since Alesina and Venturini proposed a control method for matrix converter using a mathematical approach to generate the desired output voltage [7], the PWM algorithms for matrix converters become a research focus. New PWM strategies for matrix converters have been proposed in recent years [8][9][10][11][12][13]. Some researcher concentrated on the realization of the PWM schemes, such as dipolar modulation technique [8], SHE-PWM [9], and beatless synchronous PWM [10].…”

Compared with AC-DC-AC converter, matrix converter (MC) has several advantages for its bidirectional power flow, controllable power factor, and the absence of large energy storage in dc-link. The topology of MC includes direct matrix converter (DMC) and indirect matrix converter (IMC). IMC has received great attention worldwide because of its easy implementation and safe commutation. Space vector PWM (SVM) algorithm for indirect matrix converter is realized on DSP and CPLD platform in this paper. The control of the rectifier and inverter in IMC can be decoupled because of the intermediate dc-link. The space vector modulation scheme for IMC is discussed and the PWM sequences for the rectifier and inverter are generated. And a two-step commutation of zero current switching (ZCS) in the rectifier is achieved. Input power factor of IMC can be changed by adjusting the angle of the reference current vector. Experimental tests have been conducted on a RB-IGBT based indirect matrix converter prototype. The results verify the performance of the SVM algorithm and the ability of power factor correction.
