What is a typical inverter?A typical inverter comprises of a full bridge that is constructed with four switches that are modulated using pulse width modulation (PWM) and an output filter for the high-frequency switching of the bridge, as shown in Figure 1. An inductor capacitor (LCL) output filter is used on this reference design.
What is a voltage source type inverter?Voltage source type inverters control the output voltage. A large-value capacitor is placed on the input DC line of the inverter in parallel. And the inverter acts as a voltage source. The inverter output needs to have characteristics of a current source. In the case of low impedance load, series reactors are needed for each phase.
Are voltage source type inverters easier to control?Voltage source type inverters are easier to control than current source type inverters.
