5 Frequently Asked Questions about “Three-phase inverter as buck”
What is a buck-boost DC/AC converter?
The implementation of the resulting buck-boost DC/AC converter requires only a single low-volume magnetic component and allows a seamless extension to three-phase AC/AC operation.
What is IGBT based PWM inverter?
Typically, a three-phase IGBT-based PWM inverter stage with voltage DC-link (voltage source inverter, VSI) is employed for supplying the electrical machine. The switching losses of the IGBTs and anti-parallel freewheeling diodes are limiting the switching frequency to val-ues of fs < 16 kHz, which is still within the audible range.
What is the topology of a current source inverter (CSI)?
This leads to the known topology of a current source inverter (CSI) with an input-side voltage-to-current conversion stage (see Fig. 1c, ). The system still features buck-boost capability and generates contin-uous output voltages.
How does DC Buck-stage affect a low motor speed?
Furthermore, if the input-side DC/DC buck-stage is used to shape the DC-link current according to the positive envelope of the three-phase motor currents, for low motor speeds only two out of three bridge-legs of the output stage need to be switched at any given time (2/3 modu-lation, ), which substantially reduces switching losses.
How can IGBT PWM inverters benefit from low switching frequencies?
In addition, the audible noise typical for IGBT PWM inverters operating with rel-atively low switching frequencies can be avoided, and an improvement of the part-load efficiency of the overall system, i.e., of inverter and motor, by several percentage points can be achieved.
