Abstract – A novel parallel three-level zero voltage switching (ZVS) DC converter is presented for medium voltage applications. The proposed converter includes three sub-circuits connected in parallel with the same power switches to share load current and reduce the current stress of passive components at the output side. Thus, the size of the output chokes is reduced and the switch counts in t...

An impedance-source (or impedance-fed) power converter (abbreviated as Z-source) and its control method for implementing dc-to-ac, ac-to-dc, ac-to-ac, and dc-to-dc power conversion are presented in this paper. This impedance converter employs a unique impedance network (or circuit) to couple the converter main circuit to the power source, hence provides a unique feature that cannot be obtained ...

In this paper, we use supervisory control techniques to design a protocol converter, which avoids divergence in a communication system. A typical application is to design gateways that interface heterogeneous computer networks while minimizing the communication time with the involved parties. As an example, we design a divergence-free converter that interfaces an alternating bit sender and a no...

A simple circuit technique to realize differential voltage-to-frequency converter suitable for telemetry is presented. The realization method employs second-generation current conveyors in connection with Set-Reset latch to generate the oscillating output signal whose frequency is proportional to the difference between two input voltages. The converter gain can be easily adjusted through the va...

Furthermore , the proposed converter can charge a lithium battery when an output load is light. The validity of circuit design ...

Soft switching can be achieved in the proposed converter with the proposed auxillary passive snubber circuit which is added to the conventional boost PFC converter. The converter switch is pr...

An active filter-based on-chip DC–DC voltage converter for application to distributed on-chip power supplies in multivoltage systems is described in this paper. No inductor or output capacitor is required in the proposed converter. The area of the voltage converter is therefore significantly less than that of a conventional low-dropout (LDO) regulator. Hence, the proposed circuit is appropriate...

This paper presents a method of mitigating the transient overshoots of dc–dc converters undergoing large load disturbances. The method involves a small power auxiliary circuit which exists as an energy buffer to provide a smooth absorption and release of excess energy from and to the main dc–dc converter during transients. In the method, the regulation of the current magnitude of the converter ...
