While the output voltage of a two-level PWM inverter takes either the zero or High level, three-level and multilevel PWM inverters provide the output voltage at multiple levels by dividing the input DC voltage. 7.1.1. Three-level PWM Table 7.1 compares two- and three-level inverters.
The switching of a voltage-type PWM inverter generates a neutral-point voltage, which is divided by the capacitance distributed in a motor and appears as a motor shaft voltage. The shaft voltage damages the surfaces of a motor’s metal bearings and adversely affects its quietness and service life. Let a motor’s neutral-point voltage be e0.
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.
Understanding the inverter voltage is crucial for selecting the right equipment for your power system. Inverter voltage typically falls into three main categories: 12V, 24V, and 48V. These values signify the nominal direct current (DC) input voltage required for the inverter to function optimally. What is the rated input voltage of an inverter?
Voltage source type inverters are easier to control than current source type inverters. It is easier to obtain a regulated voltage than a regulated current, and voltage source type inverters can directly adjust the voltage applied to a load by varying the conduction ratio (i.e., the pulse width of a PWM signal).
Exceeding the specified maximum input voltage for an inverter can lead to various issues. These include overheating, potential damage to internal components, and the risk of a malfunction. To mitigate these risks, manufacturers often incorporate overvoltage protection mechanisms into their inverters. How do I choose an inverter voltage?
