Title: Joseph Parisella: Innovator in Circuit Design
Introduction
Joseph Parisella is a notable inventor based in Beverly, MA (US), recognized for his contributions to circuit design and technology. With a total of 13 patents to his name, he has made significant advancements in the field of electrical engineering, particularly in the design of ballasts and power supplies for lighting applications.
Latest Patents
Among his latest patents, one is titled "Fault Condition of Detection Circuit." This invention involves a ballast that comprises an inverter with a transformer, which includes a core, a primary winding, and a secondary winding for connecting to a lamp. The ballast features a fault condition detection circuit that disables the inverter to stop energizing the lamp when a fault occurs. This circuit utilizes an additional primary winding on the transformer core to receive a voltage signal proportional to the voltage across the secondary winding. It also includes a voltage blocking circuit that selectively conducts and blocks the received voltage signal based on its frequency.
Another significant patent is "Power Supply for Halogen Lamp Having an Inverter and Output Circuit." This circuit is designed to power a halogen lamp using an inverter and an output circuit. During operation, the inverter and output circuit provide a magnitude-limited current to the halogen lamp, ensuring that the initial power is substantially less than the steady-state operating power. This design helps reduce stress on the lamp filament, thereby extending its operational life.
