The objective of this paper is to develop a SPICE- compatible equivalent circuit of a thermoelectric module. A methodology is developed for extracting the parameters of the proposed model from manufacturers' data of thermoelectric coolers (TECs) and thermoelectric generators (TEGs). The model could be helpful in analyzing the drive requirements of TECs and(More)
The problem of maximum power point tracking of high output DC voltage converters that apply Piezoelectric Transformers (PT) and voltage doublers was studied theoretically and experimentally. It was shown that the operating frequency of the PT, at which maximum voltage gain is reached, is a function of the load. Hence, under load variations, and to overcome(More)
In this paper, the applicability of the well-known single-diode equivalent circuit to modeling amorphous silicon photovoltaic modules is questioned. It is shown that, unlike in monoand polycrystalline modules, all of the equivalent circuit parameters are irradiation dependent. This dependence may be derived from either manufacturer-provided or measured I–V(More)

Signal isolation is needed in power electronics systems that include separate primary and secondary 'grounds'. The feasibility of using a piezoelectric transformer (PT) as a galvanic barrier was investigated in this study theoretically and experimentally. The research included the issues of drive, demodulation, bandwidth, and common mode rejection. In(More)
The envelope simulation method, developed earlier for large signal simulation (time domain, TRAN), is extended to include small signal envelope simulation (AC) and DC Sweep simulation (steady state for a range of carrier frequencies). The model is derived for AM, FM and PM modulation schemes and is demonstrated on a piezoelectric transformer circuit. The(More)
The envelope-simulation method, developed earlier for large-signal simulation [time domain (TRAN)] is extended to include small-signal envelope simulation (ac) and dc sweep simulation (steady state for a range of carrier frequencies). The model is derived for amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM) modulation schemes(More)
