How does an inverter perform Pulse Width Modulation (PMW)?

The core concept of PWM (Pulse Width Modulation) is to control the average output voltage by changing the pulse width of the signal. Here are the detailed steps:

  • Reference Signal (Carrier Signal): PWM inverters typically use a fixed frequency triangular wave (or sawtooth wave) as a reference signal, known as the carrier signal.

  • Modulation Signal: The modulation signal is a varying sine wave that represents the desired output AC waveform. The amplitude of the modulation signal determines the magnitude of the output voltage, while its frequency determines the frequency of the output voltage.

  • Comparison: The modulation signal is compared with the carrier signal. When the instantaneous value of the modulation signal is greater than that of the carrier signal, a high-level output is produced; otherwise, a low-level output is produced.

  • Generation of PWM Waveform: Through the above comparison process, a series of rectangular waves with varying widths are generated. The width of these rectangular waves changes over time, simulating the shape of a sine wave.

  • Filtering: Finally, a filter is used to remove the high-frequency components from the PWM waveform, resulting in a smoother sine wave output.

Research on Reliability Enhancement Scheme Implementation for Modular Intelligent Prefabricated Substations
1 Implementation Strategies for the Scheme1.1 Deepen Survey and ResearchBefore constructing prefabricated cabin - type substations, it is necessary to conduct detailed surveys of local working conditions, clarify the construction scale and objectives, evaluate existing power facilities, plan projects, make up for infrastructure shortcomings, and adjust the construction rhythm. Meanwhile, control costs to avoid project suspension.1.2 Strengthen Structural ConstructionDuring promotion, multi - dim

Comparative Analysis of 500 kV Prefabricated Substations vs. Conventional Substations
The secondary equipment area of conventional substations uses reinforced concrete or prefabricated steel structures, facing issues like long construction cycles, unreasonable functional zone design, strict environmental assessments, dust, noise, and disturbances. Primary and secondary equipment can only be installed after civil works and decoration, lowering construction efficiency.Prefabricated cabin substations integrate modularity, intelligence, and cost - effectiveness, boasting green, energ

Underground Power Cable Transmission LinesDirect - buried power cable lines have large ground - distributed capacitance, causing high single - phase - to - ground short - circuit capacitive current. For 10 kV lines, if this current exceeds 10 A, arcs hardly self - extinguish, risking arc overvoltage and endangering line equipment. Arc extinction is thus necessary.

I. Core Cause of Damage: Electrodynamic Impact (Complying with GB/T 1094.5 / IEC 60076-5)The direct cause of high-voltage winding end collapse is the instantaneous electrodynamic impact induced by short-circuit current. When a single-phase grounding fault occurs in the system (such as lightning overvoltage, insulation breakdown, etc.), the grounding transformer, as the fault current path, withstands high-amplitude and steep-rise-rate short-circuit currents.
