    摘要: A synchronous rectifier using only n-channel devices in which the low-side switches are effectively cross-coupled using low-side comparators and the high-side switches perform an accurate zero-voltage-switching (ZVS) comparison. The charging path of each bootstrap domain is completed through the low-side switches, which are each always on for every half-cycle independent of loading. This scheme gives rectifier efficiency gain because a) each bootstrap domain receives maximum charging time, and b) the charging occurs through a switch rather than a diode. Both these factors ensure the bootstrap domain is fully charged, thereby reducing conduction losses through the rectifier switches. Furthermore, settings may be adjusted by software to optimize the resistive and capacitive losses of the rectifier. Using data for die temperature and operating frequency, software can create a feedback loop, dynamically adjusting rectifier settings in order to achieve the best possible efficiency.

    摘要: A wireless power receiver IC in which the power path can be reconfigured as either a low-dropout regulator (LDO), a switched-mode power supply (SMPS) or a power switch (PSW) is provided. All three modes share the same pass device to reduce die area and share the same output terminal to reduce pin. In an inductive wireless receiver, the power path can be reprogrammed on the fly to LDO or PSW mode or can be reprogrammed on the fly to SMPS or PSW mode. In a resonant or multi-mode wireless receiver, the power path can be reprogrammed on the fly to SMPS or PSW mode. Furthermore, to achieve high power transfer efficiency performance, using N-channel MOSFET as its pass device has better efficiency and smaller die area than P-channel MOSFET pass device.

    摘要: An electromagnetic field energy recycling circuit recovers energy from a collapsing magnetic field, stores the recovered energy as charge on a capacitance, and subsequently re-uses the stored recovered energy to establish a magnetic field. Capacitance and inductance are sequentially connected in various circuit configurations to recycle the energy by a dis-continuous resonant energy transfer. In a magnetising configuration, a magnetic field is established by transfer of energy stored on a capacitance to an inductance. In a field energy recovery configuration, a capacitance is charged with energy recovered from the inductance on collapse of the magnetic field. In a third configuration, the recovered energy stored by the capacitance is held until required for establishing a magnetic field. During the magnetising configuration, voltage on the capacitance drops by at least 50% and preferably to zero. During the recovery configuration, current flowing in the inductance falls to zero. The circuit can be used to drive electromagnetic devices, eg electric motors, generators, transformers, solenoids, induction heating coils and inductive power transfer windings.

The circuit comprises: a single current sense input connected to a current sense r esistor via a second resistor, for coupling in series with a power switch to generate a current sense signal for current through the switch; first and second comparators sharing a connection to the current sense input and having respective first and second outputs coupled to a controller, these being configured to compare a voltage on said shared input connection against different respective first and second threshold values; and a current generator coupled to said shared input connection. This enables third and fourth bi - level current sense threshold values to be set independently by said current sense and second resistors without changing said first and second threshold values.
