Latest Patents
One of Ashish Kumar's latest patents is titled "Power transfer over an isolated capacitive barrier with controlled current." This invention involves capacitively isolated current-loaded or current-driven charge pump circuits and related methods that transfer electrical energy from a primary side to a secondary side over a capacitive isolation boundary. The innovation utilizes a controlled current source to charge isolation capacitors with constant current, maintaining output voltage within tolerance. These charge pump circuits serve as DC-to-DC converters, particularly useful in isolated power supplies for low-power applications, such as sensor transmitters with separate electrical ground planes. The methods developed by Kumar efficiently transfer electrical energy over an isolated capacitive barrier, reducing electromagnetic interference (EMI) and overall costs.
Another significant patent is "Active noise filtering for switch mode power supplies." This invention describes a circuit that includes a sensor, a controller, and an amplifier. The sensor is designed to be coupled to the chassis of a switch-mode power supply (SMPS). The controller processes the sensor output, while the amplifier provides compensation pulses to reduce common-mode noise on the chassis. This innovation enhances the performance of switch-mode power supplies by effectively managing noise levels.
