Latest Patents

One of Shaobin Wu's key patents is titled "LED driver with small output ripple without requiring a high-voltage primary-side electrolytic capacitor." This invention focuses on a power converter that reduces output ripple without the need for an electrolytic primary-side capacitor, which can negatively impact product lifespan. The design utilizes Primary-Side Regulation (PSR) with an auxiliary winding to maintain a regulated secondary voltage while minimizing low-frequency ripple. A smaller secondary capacitor, which is not an electrolytic type, effectively filters the output on the secondary side. The invention also incorporates a bang-bang controller that manages the secondary side current, thereby reducing current ripple despite the presence of voltage ripple.
