power quality, cable losses, harmonics, inverter losses,
Nowadays, both active and passive front end rectifiers are used in modern inverter systems. Active front-ends, using high switching frequencies, create extra switching losses compared to passive front ends. However, using active front-ends, a power factor up to 1 and a negligible harmonic content of the loading current can be achieved, resulting in lower cable losses. This contribution analyses the weight of both inverter and cable losses with the aim to optimise all over power losses in a drive system.
