Twintex PCH 6000V (6kV) high voltage DC power supplies, rated at power levels of 10kW to 75kW, are primarily used for burn-in testing of industrial-grade or system-level devices that demand exceptional resilience against power and voltage stress. Unlike low-power testing of individual components, these applications focus on verifying the long-term reliability and stability of the entire system.
- Power semiconductor devices: This is a core application of PCH 6000V (6kV) high voltage DC power supplies. These power supplies can be integrated into burn-in testing systems of IGBTs, MOSFETs, and diodes, as well as emerging high-voltage, high-power devices such as Silicon Carbide (SiC) and Gallium Nitride (GaN) components. Testing involves applying rated (or higher) voltage and current combined with temperature & humidity control to evaluate performance degradation and lifespan under prolonged high-voltage, high-power operation.
- High-voltage capacitors: PCH 6000V (6kV) high voltage DC power supplies can be used for burn-in testing of high-voltage power capacitors, supercapacitors, and similar components. Long-duration charge-discharge cycles or continuous operation at rated high voltage are employed to assess capacitance degradation, changes in equivalent series resistance (ESR), and the long-term stability of insulation performance.
- Power and distribution equipment: PCH 6000V (6kV) high voltage DC power supplies can be used to verify the reliability of critical equipment within power systems. Such as long-term withstand-voltage burn-in tests for high-voltage cables, transformers, switchgear, instrument transformers, and insulators. Continuous application of high voltage simulates years of electric field stress experienced in the power grid, allowing for the evaluation of insulation aging rates and expected service life.
- Industrial and specialized electronic equipment: In specialized sectors, PCH 6000V (6kV) high voltage DC power supplies are used for burn-in testing of high-voltage electron tubes, gas discharge tubes, high-power variable frequency drives (VFDs), and avionics, ensuring reliability under rigorous operating conditions.
The PCH 6000V (6kV) high voltage DC power supplies typically operate in two modes during burn-in testing.
- Continuous energization burn-in: Applying rated (or slightly higher) voltage/current to the device under test (DUT) for an extended period to simulate the aging process under normal operating conditions.
- Cyclic stress burn-in: Simulating more rigorous operating conditions. Examples include high/low-temperature cycling or cyclic load testing, where the load or ambient temperature is periodically varied while high voltage is applied, thereby accelerating product aging.
