IGBT Module: Core inverter component of the IGBT power supply, responsible for converting DC power to medium-frequency AC power with high efficiency and stable switching control.
Rectifier Bridge: Converts three-phase 50Hz AC power into stable DC power, ensuring reliable input for the inverter stage.
Resonant Capacitor: Forms a resonant circuit with the induction coil, realizing reactive power compensation and optimizing power factor (≥0.97).
Smoothing Reactor: Stabilizes DC bus voltage, suppresses current surges and filters harmonics to protect core components.
Driver Board: Provides gate drive voltage (15V ON/-5V OFF) for IGBT modules, transmits control signals and feeds back fault status.
Control Board: Central control unit with DSP chip, adjusting output power, frequency and operating parameters to adapt to different industrial scenarios.
Protection Circuit: Integrates overcurrent, overvoltage, overheating, low water pressure and short-circuit protection (response time ≤8μs) to avoid component damage.
Water Cooling System: Main heat dissipation component for IGBT modules and rectifier bridges, ensuring operating temperature ≤150℃ (IGBT junction temperature).
Auxiliary Power Supply: Provides stable DC 24V power for control boards and driver boards to ensure normal operation.
Terminals & Copper Bars: Used for electrical connection between components, ensuring low contact resistance and efficient power transmission.
