Kebutuhan energi listrik domestik mayoritas berbentuk gelombang sinusoida pada frekuensi 50 Hz. Sumber terbarukan dc atau daya dengan tidak terkontrol. Untuk itu diperlukan alat yang dapat mengontrol bentuk dan frekuensinya. Alat ini disebut inverter. Inti dari inverter terletak kontrol switching, dimana ditentukan ini, salah satunya adalah SPWM. Dipasaran tersedia pembangkit SPWM seri EGS-002,...

This paper focus on the advancement of SVPWM (space vector pulse width modulation) inverter fed permanent magnet synchronous motor (PMSM).The paper deals with a space vector pulse width modulation (SVPWM) algorithm applied to electrical drives. Anextensive and detailed study of the space vector pulse width modulation design process hasbeen done, that indicate some practical sign for implementat...

Human subjects performed step-tracking movements of the wrist in the radial direction. Movement amplitude, external load, and accuracy instructions were varied. We used surface electrodes to record muscle activity from an agonist, extensor carpi radialis longus, and an antagonist, extensor carpi ulnaris. When subjects performed movements “as fast as possible” that were opposed by different exte...

Photoplethysmography (PPG) technology has been used to develop small, wearable, pulse rate sensors. These devices, consisting of infrared light-emitting diodes (LEDs) and photodetectors, offer a simple, reliable, low-cost means of monitoring the pulse rate noninvasively. Recent advances in optical technology have facilitated the use of high-intensity green LEDs for PPG, increasing the adoption ...

The simple Selective Harmonic Elimination (SHE) for 3-Phase Voltage Source Inverter (VSI) is presented here. The proposed work is to examine the Selective Harmonic Elimination (SHE) and to eliminate harmonics produced by Pulse Width Modulation (PWM) inverter. The selective harmonic elimination method for three phase Voltage Source Inverter (VSI) is generally based on ideas of opposite harmonic ...
