Title: Bruce R Wrenbeck: Innovator in Power Delivery Circuits

Introduction

Bruce R Wrenbeck is a notable inventor based in Dearborn, MI (US). He has made significant contributions to the field of electrical engineering, particularly in the development of power delivery circuits. With a total of 6 patents to his name, Wrenbeck's innovations have had a lasting impact on the industry.

Latest Patents

One of Wrenbeck's latest patents is a pulse width modulation and protection circuit. This circuit includes a transistor pass element that is alternately switched on and off by an oscillator, connecting a power source to a load. The current through the transistor pass element is compared to a reference signal by a comparator. If the current exceeds the reference signal, the comparator generates a fault signal, switching off the transistor pass element for the remainder of the cycle. After a predetermined number of faults, the transistor is switched off for multiple cycles. This design prevents damage to the transistor pass element and allows for downsizing, ultimately saving product costs.

Another significant patent is related to a device in a power delivery circuit. This improved current sensing circuit is designed for use with a current controlling device that includes auxiliary current sensing terminals. It is particularly useful in conjunction with a current sensing power MOSFET located in the high side of a switching circuit, such as an H-bridge switch for a bidirectional load. The current sensing circuit has two branches connected to the current sensing MOSFET and provides an output voltage signal representative of the main current through the MOSFET. This innovative design enhances the efficiency and reliability of power delivery systems.
