With a total of four patents to his name, his innovative spirit has propelled advancements in electronic circuits, particularly those related to switching power transistors.
Latest Patents: Among his latest inventions, Harold has developed two notable patents that exemplify his ingenuity. The first is a **Transistor Drive Circuit**, which introduces a drive current circuit designed for a switching power transistor. This invention enables the controlled turn-off of the transistor without disrupting its turn-on process. The drive transformer utilized in this innovation features two cores, one adhering to a linear magnetization characteristic while the other has a higher permeability. By incorporating both input and output windings on both cores and including a turn-off winding on the higher permeability core, the circuit facilitates controlled turn-off through the shorting of the turn-off winding, directly coupling a source of turn-off charge to the transistor.
The second patent, titled **Semiconductor Switching Circuit with Clamping and Energy Recovery**, focuses on a circuit engineered to manage the voltage across a rapidly switched semiconductor element, such as a transistor, within an inductive circuit. This circuit is designed to stabilize the voltage to nearly double that of the input source when the semiconductor element transitions to its nonconducting state. Additionally, it encompasses circuitry capable of recovering and returning stored energy from the inductance and wiring back to the input source.
