This paper presents a regenerative cascade inverter topology with direct active power control scheme. From the mathematical model of the proposed regenerative cascade inverter, the instantaneous active power and reactive power are derived. Based on the instantaneous abc theory, direct active power feed-forward control is proposed to reduce AC power and voltage fluctuation in DC link. Moreover, ...

An optical probe current sensor module using the Kerr effect of exchange-coupled magnetic film has been fabricated and applied to switching current measurements for IGBT used for the DC-DC converter and the DC-AC inverter of EV/HEV. Since the sensor module using the Kerr effect of the single domain exchange-coupled magnetic film utilizes magnetization rotation only, Barkhausen noise due to doma...

<p>The traction inverter is a crucial power device in the electric vehicle’s powertrain, and its failure intolerable as it would considerably compromise system’s safety. For more reliable driving, installing that sufficiently resistant to electrical inherent. Due compact size small number of switches incorporated three-phase four-switch inverter, this modular topology was used compensate ...

This article proposes a topology for construction of multilevel inverter consisting of H-bridge and level switch. In accordance with the proposed topology Н-bridge inverts voltage and a switch enables to get any number of voltage levels. At that, in comparison with analogues, the above mentioned topology allows saving on expensive power keys. Moreover, a special technique has been developed to ...

An image sensor comprising an array of 128 by 50 super pixels, column parallel current conveyors and global difference double sampling (DDS) unit is presented. The super pixel consists of: a reset transistor, a readout transistor, four transfer transistors and four photodiodes. The photo pixel address switch is placed outside the pixel, effectively implementing 1.5 transistors per pixel using a...

The class Φ2 inverter is a new switched mode type of resonant inverter. This inverter is applicable for very high frequency application. In this paper, it proposes class Φ2 inverter reduced the voltage stress, and improve the dynamic response. The class E resonant inverter is not suitable for high frequency application, because it produce high voltage stress across the switch. The suitable ball...
