This paper proposes an isolated DC-DC converter for Power-Supply on chip (SoC) realized by the couple of air-core coils. The pro-posed isolated DC-DC converter is evaluated by numerical simulations and experimental results. The fabricated prototype DC-DC converter works well and the simulation results are good agreement with experimental results. This paper also discusses the potential of proposed...
In this paper, we propose a concept of Field Programmable Power supply Array (FPPA), which is a fully digital controlled power supply, based on power supply on chip technology. The FPPA realize multi input voltage and multi output voltage only rewrite digital code of FPGA or DSP.
In DC power supply system, a fast response circuit breaker is required. Semiconductor DC circuit breaker is an important key technology in DC power supply system. This paper considers the malfunction issue of Silicon Carbide-Static Induction Transistor (SiC-SIT) based DC circuit breaker in DC power supply system. The malfunction mechanism is explained, and a solution methodology proposed. Investigations...
This paper considers the malfunction mechanism of semiconductor circuit breaker in high voltage DC power supply system (HVDC). In HVDC system, the fast response breaker is required. Semiconductor circuit breaker is paid attention as one of the key technology in HVDC. However, in some condition, the semiconductor circuit is malfunctioned. When malfunction is happened, unexpected large current is flown...
