20150188328 | CHARGING CIRCUIT, AN INDUCTIVE LOAD CONTROL CIRCUIT, AN INTERNAL COMBUSTION ENGINE, A VEHICLE AND A METHOD OF CHARGING A BOOTSTRAP STORAGE ELEMENT - A charging circuit for a bootstrap capacitor comprises a P MOSFET having a body diode and an N channel power MOSFET also having a body diode. The drain of the P MOSFET is coupled to the source of the N channel power MOSFET, and the source of the P MOSFET receives current from a vehicle's battery. The gate of the P MOSFET receives a control signal for turning the P MOSFET either on or off and the drain of the N channel power MOSFET is connected to a bootstrap capacitor The P MOSFET's body diode prevents current flow from the battery to the bootstrap capacitor when the P MOSFET is turned off and the N MOSFET's body diode prevents current flow from the bootstrap capacitor to the battery when the N MOSFET is turned off. The use of a power MOSFET device with its low ON resistance ensures that the capacitor is charged to a sufficiently high voltage even under low battery conditions. | 07-02-2015 |
20150241901 | POWER SUPPLY CONTROL DEVICE - An electronic device is for controlling multiple switching power circuits in a power supply system. Each switching power circuit has a power clock for controlling switching of a supply side switch that enables charging. The device has respective power clock delay units. Each respective power clock delay unit provides a respective power clock at a predetermined delay based on a respective input clock. The respective predetermined delays are chosen so that said switching of respective different supply side switches occurs at respective different points in time. Advantageously the conducted emission in high frequency bands is reduced. | 08-27-2015 |
