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)
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, de-modulation, 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)

In various applications, thermoelectric active cooling systems can help maintain electronic devices at a desired temperature condition better than passive coolers. Thermoelectric Coolers (TEC) are especially useful when the temperature of a device needs to be precisely controlled. This study proposes a user-friendly graphical method for calculating the(More)
