摘要： A high voltage offset detection circuit registers the voltage at the midpoint of a switching half-bridge and may determine when the midpoint voltage reaches a given value to avoid hard-switching in the half-bridge switches. The midpoint voltage of the switching half-bridge is applied through a buffer to a MOSFET that is current limited to produce a voltage that reflects the voltage of the midpoint of the switching half-bridge. The voltage produced by the MOSFET may be supplied to a comparator with a threshold input to obtain a signal that indicates when the switches of the switching half-bridge may be turned on to avoid hard-switching. An adaptive dead-time circuit and method may comprise the above sensing circuit, a first circuit for generating a first signal indicative of a high to low transition of the midpoint voltage; and an output circuit for generating an adaptive dead-time output signal based thereon. A second circuit may generate a second signal indicative of a low to high transition of the voltage; wherein the output circuit generates the adaptive dead-time output signal based on both the first and second signals. The second circuit preferably generates the second signal by reproducing the first signal. The first circuit may generate the first signal by charging a capacitor in response to pulses, and the second circuit may generate the second signal by charging a second capacitor corresponding to said first capacitor, and the adaptive dead-time output signal may be responsive to the charges on the first and second capacitors.

摘要： An on/off control circuit is provided that controls the application of power to a device. The effectiveness of the on/off control circuit is optimized with regard to cost, power consumption, component life, and utility. An R-C circuit is used to provide a time-delayed turn-on, and turn-off, of the device being controlled, accompanied by a latch that retains the on/off state and controls the coupling of a power source to the device being controlled. The latch is configured as a data flip-flop (DFF) with a clocking signal that is controlled by the time-delayed switch input. The flip-flop has an inverted output signal as its input, thereby providing a toggled on/off operation. The latch also includes an independent reset input, thereby allowing an independent turn-off operation by power management controllers within the device being controlled. In the quiescent state, the preferred embodiment consumes less than half a microWatt of power.

摘要： A driver circuit has a gate drive terminal that produces a gate drive signal to control paralleled power semiconductor switches, such as GaN high electron mobility transistor (HEMT) devices. One of the switches is closest to the gate drive terminal such that its gate drive loop inductance is smaller than the remaining switches that are farther away having a larger loop inductance. An additional resistor or gate-source capacitor is provided in the gate drive circuit of the closest switch which increases the total gate resistance of the closest switch compared to the remaining switches, which delays the turn off time of the closest switch. The delay permits zero voltage switching turn-off of the remaining switches to reduce noise. The closest switch is hard switched off but has the smallest loop inductance, which allows optimized turn off.

摘要： A solid state switching device (SSSD) for AC and DC high power solid state power controller includes, for DC applications, a MOSFET and an IGBT connected in parallel and an optional zener diode connecting a collector and a gate of the IGBT. For AC applications, the SSSD includes a "back to back" pair of MOSFETs connected in parallel with a pair of counter-parallel IGBTs, each in series with a diode, and, optionally, zener diodes "back to back" with conventional diodes connecting a collector and a gate of each of the IGBT. A method of switching establishes a sequence of turning on/off the MOSFET(s) and the IGBT(s) wherein the IGBT(s) turn on before and turn off after the MOSFET(s). A negative feedback prevents a voltage of SSSD rising above predetermined level.

摘要： A solid-state alternating current (AC) switch provides for the sequential turn-on of the associated solid-state switches (14a, 14b, 14c) to reduce the generation of electromagnetic interference (EMI). The solid-state AC switch includes at least first and second solid-state switches (Q1, Q2, Q3, Q4, Q5, Q6) connected in series between an AC input (A, B, C) and an AC load (20). A zero-cross detector circuit (18) monitors the AC input to determine zero-crossings associated with the monitored AC input. A controller (16) turns on the first solid-state switch and the second solid-state switch according to a turn-on sequence in which the first transistor is turned ON during a detected zero-crossing window associated with the first transistor and the second transistor is subsequently turned ON during a detected zero-crossing associated with the second transistor.
