Maximum Constant Boost Control of SL-Z-Source Inverter

This paper explores Switched Inductor (SL) Zsource inverter which adjusts the voltage and have application in Fuel cells (FCs) which have achieved global attention as an alternative power source for hybrid electric vehicles (HEVs). The proposed inverter uses inductor and capacitor circuit to join the source and load circuit. On comparing with the initial Z-source inverter, the explored circuit ...

three phase on-line ups by implementing t-source inverter with maximum constant boost pwm control

this paper presents the new topology of three phase on line uninterruptible power supply (ups) by employing t-source inverter (tsi) with maximum constant boost pulse width modulation (pwm) control and the results are compared with the conventional uninterruptible power supply (ups). the conventional ups consists of voltage source inverter (vsi) with step up transformer or dc-dc booster which de...

Sliding Mode Control of a Bidirectional Buck/Boost DC-DC Converter with Constant Switching Frequency

In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...

Minimum Switching Frequency and Maximum Power Factor

This paper presents a unique PWM switching pattern and a novel power factor control scheme for high power GTO ac/dc converters. This switching pattern has a switching frequency of 360Hz, which is the lowest possible frequency to achieve 5th and 7th harmonic elimination and an adjustable dc output current simultaneously. Using both feedback and feedforward control techniques, the proposed power ...
