The high-frequency pulses pass through the transformer. This step steps down the voltage while providing a safety barrier between the "hot" AC side and the "cold" DC output side. 4. Secondary Rectification & Filtering

Once filtered, the AC voltage must be converted into high-voltage DC.

Typically a 3.15A/250V slow-blow ceramic fuse protecting against catastrophic short circuits.

This exclusive technical breakdown explores the architecture, functional blocks, and comprehensive troubleshooting protocols derived directly from the Wannien 101V0 Power Supply Schematic on Scribd . Core Architectural Blocks of the Wannien 101V0

A high-capacity aluminum electrolytic filter capacitor (typically rated at 400V or 450V) smooths the rippling DC string into a stable high-voltage DC bus. The Switching Heart: PWM Controller and Power MOSFET

The AC voltage from the main transformer is rectified by a series of output rectifiers. Schottky diodes are commonly used here due to their high efficiency. Test each one with your multimeter for shorts or opens.

Once filtered, raw AC voltage meets the . The high-frequency pulses pass through the transformer

The Wannien 101V0 schematic represents a cost-optimized, high-reliability design intended for consumer electronics. The absence of an optocoupler reduces component count but places the burden of regulation accuracy on the PWM controller's internal algorithms. When troubleshooting, focus on the high-voltage startup resistors and the current-sensing resistors, as these are the most common points of failure in this specific topology.

Unlike cheaper supplies, the Wannien 101v0 includes a located at RV1 on the schematic. This clamps voltage spikes. Directly behind it is a common-mode choke (L1) with a 20mH rating. Exclusive tip: If the supply is dead but the fuse is okay, check RV1 for a short circuit.

To safely split power across diverse electronics, the circuit splits into a mainboard supply and an inverter/backlight path. An optocoupler bridges the gap between the primary and secondary stages, sending error signals back to the PWM controller to constantly maintain output precision. The secondary side relies on high-speed Schottky rectifiers and a multi-transistor configuration to manage individual power lines: Wannien 101v0 Power Supply Schematic | PDF - Scribd
