Performance characteristics of the 28V DC starter power supply:

• The power semiconductor devices utilize a next-generation IGBT, leveraging the high-frequency, low-loss characteristics of the IGBT’s switching operation mode to perform electrical energy conversion; these devices feature a compact size, light weight, high efficiency, and high reliability;
• The current-mode control employs a full-bridge converter topology, PWM control, and slope compensation technology; it does not require a series anti-commutation capacitor, offering advantages such as fast dynamic response, strong resistance to impact loads, and reliable overcurrent protection;
• The LED panel displays power operating parameters and the current operating status; it features a self-diagnostic function that can record recently occurred faults, thereby enhancing maintainability;
• All functional units and components are designed with a modular architecture; by cascading these components for scalability, the system achieves a compact size, high efficiency, excellent reliability, and superior maintainability.

Advantages and disadvantages of 28V DC starting power supply:

• Suitable applications: engine startup, motor testing;
• Product advantages: compact size, lightweight, low cost, and high impact resistance;
• Product drawbacks: The output ripple of linear power supplies is relatively high.
