The MOSFET chops the pulsating DC at high frequency (typically 60kHz–100kHz). This action charges a large, high-voltage electrolytic capacitor (usually rated for 420V or 450V). This reservoir capacitor maintains a steady 380V to 400V DC bus , completely isolated from input AC voltage fluctuations. Phase 3: The Standby & Pulse Width Modulation (PWM) Stages

A dedicated monitoring chip constantly tracks the lines for unsafe states, triggering an immediate shutdown if thresholds are crossed: OVP / UVP: Over-Voltage and Under-Voltage Protection. OCP / SCP: Over-Current and Short-Circuit Protection. Troubleshooting Common Component Failures
The PS-4241-9HA schematic heavily implements a for its main power path. Rather than employing harsh hard-switching techniques that bleed thermal energy, the resonant tank circuit enables Zero Voltage Switching (ZVS) . This design choice is the cornerstone of why the power supply hits over 90% efficiency under typical operating loads—it significantly minimizes switching losses across the primary switching transistors. The MOSFET chops the pulsating DC at high
