This model shows a three-phase voltage source inverter (VSI). The VSI is an inverter circuit which cre-ates AC current and voltage from a DC voltage source. Three different Pulse-Width Modulation (PWM) schemes are presented for controlling the VSI output. The system is designed to achieve a power rating of 10 kW.
(VSC) is an indispensable part of a variety of power electronic systems. It finds application in motor drives, power facto correcting equipment, grid integration of renewable energy sources etc. Among other types of inverters, Voltage Source Inverte (VSI) is more efficient, more robust and gives faster dynamic response. Due to t
The VSI is an inverter circuit which cre-ates AC current and voltage from a DC voltage source. Three different Pulse-Width Modulation (PWM) schemes are presented for controlling the VSI output. The system is designed to achieve a power rating of 10 kW. A 700 V DC voltage source supplies power to the inverter.
esign of a 2-level, 3-phase Voltage Source Converter (VSC) is explained. A 10kVA, 415V 3-pha e VSC has been designed, fabricated and tested in the labs in IIT Delhi. The design of VSC constitutes the gate driver circuit, gate pulse divider circuit, power circu
This is an example of a Grid-Connected VSC with P Control. The converter links a 3‐phase ac source to a dc load/source through a voltage‐sourced converter (VSC). The VSC comprises 6 IGBT‐diode pairs, which form a 2‐level 3‐pole bridge.
1980-Hz 3-level 3-phase VSC. The VSC converts the 500 V DC link voltage to 260 V AC and keeps unity power factor. The VSC control system uses two control loops: an external control loop which regulates DC link voltage to +/- 250 V and an internal control loop which regulates Id and Iq grid currents (active and reactive current components).
