A three-phase Voltage Source Inverter (VSI) with SPWM (Sinusoidal Pulse Width Modulation) is a type of inverter that converts DC voltage into three-phase AC voltage with sinusoidal waveforms. It works by varying the pulse width of a high-frequency carrier signal according to the instantaneous amplitude of a reference sinusoidal waveform.
3-phase pure sine wave DC-AC inverters employ the latest silicon carbide (SiC) semiconductor technology to deliver high efficiency and high power density The CTP 1000-F7W ultra-compact, low profile DC-AC inverters deliver up to 1000VA 3-phase pure sine output voltage.
In a 3-phase inverter, three separate SPWM signals are generated for each phase, By comparing a high-frequency triangular waveform with three sinusoidal reference waveforms (one for each phase) to determine the pulse widths of the inverter''s switching devices.
A three-phase VSI consists of six power semiconductor switches, typically insulated-gate bipolar transistors (IGBTs) or power MOSFETs, arranged in an H-bridge configuration. The switches are grouped into three pairs, each controlling one phase of the output voltage (Va, Vb, and Vc).
Our solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
