6 FAQs about Large-scale Solar Power Generation & Energy Storage

What are the different types of PWM inverters?

PWM inverters can be broadly categorized into single-phase and three-phase types, each with distinct structures and applications. Single-phase PWM inverters consist of two main parts, the DC power source and the inverter bridge, typically use a full-bridge configuration consisting of four power switches, usually IGBTs and MOSFETs.

How does a PWM inverter work?

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.

How a PWM controller is used in a battery inverter?
