A fast–response sliding–mode controller for quadratic buck converter
The switched–mode power supplies are widely used in very low voltage and high–power applications where large conversion ratios are required. In such cases, the quadratic buck converter is the suitable one compared to buck, cascaded buck and multi–phase choppers, because of their limitations in switching frequency and losses. This paper presents mathematical analysis, design and simulation of a ...

What is HV and LV Power Distribution System?
An HV power distribution system simply means a high voltage distribution system while an LV is a low voltage or tension power distribution system. LV power supply can be around 230 Volts for a single-phase connection and 400 Volts for a three-phase connection. On the other hand, the HV distribution system can even reach 11Kilo-Volts, meaning it is highly used by bulk power purchasers like ...

Power losses from wind generated electricity in high voltage AC transmission: an analysis through simulation
In this paper, we have investigated different types of losses from wind generated electricity in high voltage AC (HVAC) transmission. Wind power generation is expensive in nature and it is thus necessary to know how much power is lost in the transmission. We have simulated an HVAC transmission system with a wind power generator in Simulink. We varied different components of the system namely wind ...

Switched-coupled-inductor DC/DC converters with high voltage conversion ratio
When a low voltage DC power source is used, a DC-DC converter with a high step-up voltage gain is required to raise the voltage to more applicable levels. This is typically achieved by using classical converters driven by pulse width modulation (PWM) waves with extremely high duty cycles. Although theoretically step-up converters can achieve an infinite gain as the duty cycle approaches unity, in ...
