The installed capacity of photovoltaic (PV) systems globally reached 177 GW at the end of
2014. The annual rate of installations, 38.7 GW in 2014, continues to increase. A large part …

Electrolytic capacitor with a dc-side inductor is a typical dc-link filtering configuration in grid-
connected diode rectified adjustable speed drives (ASDs). The criteria to size the dc-link …

In conventional motor drive systems using pulsewidth modulation (PWM) inverters, large
electrolytic capacitors are used for stabilization of the dc-link voltage. Since the electrolytic …

This paper explores the use of GaN power FETs to realize an integrated modular motor drive
(IMMD) with an induction motor. A structure in which inverter modules are connected in …

DC-link electrolytic capacitor critically affects the lifetime of the motor drive system. This
paper proposes an inverter power control strategy based on dc-link voltage regulation for …

If a small dc-link capacitor is used in the dc link fed by a single-phase ac source, then the dc-
link voltage severely fluctuates at twice of the source frequency. To handle this fluctuation …

Harmonic emissions have been changed in distribution networks, with respect to frequency
range and magnitude, due to the penetration of modern power electronics systems. Two …

This paper describes motor drive system fed by a single-phase diode rectifier without power
factor correction (PFC) circuit or the input filter. The system considered in this paper consists …

A small dc-link capacitor based drive system shows instability when it is operated with large
input line inductance at operating points with high power. This paper presents a simple, new …
