An on-chip voltage supply regulator for subthreshold-operated CMOS logic LSIs is proposed. The regulator transforms lithium battery voltage 3 V to low supply voltage 0.4-0.5 V for subthreshold-operated CMOS logic LSIs. It monitors the gate delay in the LSI and produces an appropriate supply voltage such that the delay is equal to a value determined by a built-in capacitor-resistor reference. We...
In this paper, the stand-alone photovoltaic system for cathodic protection of underground pipelines is presented. The proposed system offers continuous and automatic adjustment of the applied voltage so that the buried pipelines receive the exact current. A modified perturb and observe (P&O) algorithm for maximum power point tracking (MPPT) is used to improve dynamic and steady state performa...

An integrated buck converter that operates under low voltage environment with fast transient response is presented. The designed buck regulator employs derivative output ripple voltage for sensing current. It is targeted to be fabricated with 180nm UMC technology at 2MHz switching frequency. The response time is less than 2.2μ Sec. The regulator provides an output voltage of 1.8V against the ba...
The sale of hybrid electric vehicles (HEVs) has increased 10 fold from the year 2001 to 2008 [1]. Thus, high temperature electronics for HEV applications are desired in the engine compartment, power train, and brakes where the ambient temperature normally exceeds 150°C. Power converters (i.e. DC-DC converter, DC-AC inverter) inside the HEVs require Gate-Driver ICs to control the power switches....
This paper presents the application of immune algorithm to find optimal location and sizing for distributed generation (DG) sources and static series voltage regulator (SSVR) in distribution networks. The proposed objective function for this allocation includes investment costs and profits accrued from reduced losses and also included is a set of quality indexes that show the status of voltage,...
Generator merupakan salah satu bagian dari sistem tenaga listrik yang digunakan untuk mengkonversi energi mekanik berasal putaran turbin menjadi dengan memanfaatkan gaya gerak listrik. Eksitasi paling krusial pada berperan menghasilkan fluks berubah terhadap waktu, sehingga dihasilkan GGL induksi. Arus penguatan mengatur besarnya tegangan keluaran sesuai pembebanan diterapkan. Adapun alat arus ...
