Title: Innovations by Josh Mandelcorn
Introduction
Josh Mandelcorn is an accomplished inventor based in Los Angeles, CA. He holds a total of 4 patents that showcase his expertise in power supply technologies. His innovative contributions have made a significant impact in the field of electrical engineering.
Latest Patents
One of his latest patents is a "Status Indicating Circuit for Paralleled Switching Power Supplies." This invention features a keep-alive circuit designed for a regulated switched-type power supply. It ensures that the power supply generates power pulses even under conditions where the output voltage level would typically cause the regulator circuit to reduce power pulses to zero. The keep-alive circuitry detects the absence of power pulses over a predetermined time interval and modifies the regulating circuit to respond to a different output voltage level, thereby forcing the power supply to generate power pulses. This cyclic action results in a series of low-frequency power pulses, indicating that the power supply is still operational.
Another notable patent is the "Unity Power Factor Power Supply." This invention includes a boost converter connected to the alternating current line. It is controlled to draw sinusoidal current from the line by operating as a current regulator. The current reference control signal tracks the line voltage waveform, minimizing the required input current for a given power output.
