Development of a Thermal Voltage Converter with Calculable High-Frequency Characteristics
نویسندگان
چکیده
High-frequency characteristic of a TVC-input circuit becomes dominant factor in the AC-DC transfer difference at frequencies higher than 100 kHz. In order to evaluate the high-frequency characteristics of TC modules up to 1 MHz, a High-Frequency-standard TVC (HF-TVC) has been developed at AIST, in collaboration with Nikkohm Co. Ltd. The HF-TVC is designed such that the frequency characteristic is calculable from the shape and dimension of the input circuit. The thermal converter element (JSTC04) has a simple straight heater configuration, which reduces the parasitic impedance in the heater pattern. The Built-In TEE (Internal TEE) configuration has been used to avoid the effects from parasitic impedance in the input leads.

متن کاملHigh voltage gain DC-DC resonant converter
In this paper, a DC-DC resonant converter with high voltage gain and small size is studied. To reduce the size and weight of this converter, the operating frequency should be as high as possible. In this research, the frequency changes from 120 to 200 kHz. Due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. Resonant converters are su...

متن کاملDesign and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...
