Free QuoteThe power losses in a voltage source inverter (VSI) are the sum of the additional constant power losses of the local power supply, the inverter circuits as well as the main power conversion losses.
The process of selecting the topology, components and operating parameters (voltage, current and switching frequency) of an inverter is highly affected by the anticipated inverter losses. An accurate estimate of the losses occurring in each part of an inverter can significantly contribute to achieving an enhanced inverter design.
This paper examines the semiconductor and DC-link capacitor losses of four voltage source inverter topologies: the conventional two-level inverter, the two-level two-channel interleaved inverter, the three-level Neutral-Point-Clamped (NPC) inverter and the three-level Cascaded H-Bridge inverter, shown in Figure 1.
Losses in two-level inverters have been reported extensively in the literature. Researchers have also investigated semiconductor losses in three-level inverters. Estimates of switching losses have been obtained using approximations of IGBT and diode I-V switching characteristics [1, 4, 17, 18].
The two-level two-channel interleaved inverter losses are examined under the assumption that the instantaneous current carried by each of the inverter channels is approximately half of the respective phase current. Leg (channel) inductors and sufficiently high switching frequencies are used to satisfy this requirement.
Switching losses phase angle [9, can result in in a three-level NPC inverter have been investigated in, using a second order approximation of the IGBT and diode Esw-I characteristics.
