摘要： A method for power plane splitting. The method enables the traces on a power plane to be organized so that the conductor area is expanded while still ensuring that components with similar power supply requirements are coupled to the same trace. A potential field of a power plane of a printed circuit board is calculated by assigning one or more potential values to one or more components coupled to the printed circuit board and solving for a plurality of potential field values at a plurality of locations between the one or more components. One or more boundaries between the one or more components are defined by selecting contours of constant potential within the calculated potential field. One or more traces on the power plane are created using the one or more boundaries, wherein the one or more traces connect a corresponding one or more pluralities of components and each plurality of components of the one or more.

摘要： This invention relates to new soft-switching techniques for minimizing switching losses and stress in power electronic circuits using inverter legs. By choosing the switching frequency with specific relationships with the resonant frequency of the power electronic circuits, the proposed switching technique enables the power electronic circuits to achieve soft switching under full load and short-circuit conditions at the defined frequencies for both capacitive and inductive loads. This technique can be applied to an electronic circuit with two switches connected in totem pole configuration between two dc voltage rails or commonly known as a power inverter leg or inverter arm. Examples of these circuits are class-D power converter, half-bridge power converters and full-bridge power converters or inverters. The proposed techniques allow inverter circuits with resistive, capacitive and inductive loads to achieve soft switching.

摘要： An adder 11 outputs a signal VS indicating a value of (VrnullVo), and a multiplier 12 outputs a control signal GS indicating a value of G(VrnullVo) on the basis of the signal VS. An adder 13 outputs a signal HS on the basis of the control signal GS and a signal FS outputted from an operation circuit 30, and a PWM signal generating circuit 20 generates a PWM signal KS on the basis of the signal HS and a ramp signal RS outputted from a ramp signal circuit 15, and outputs this signal KS to a switching power supply. A counter 14 counts an on time of the PWM signal KS and retains a count value at a time of receiving a sample signal SMP. The operation circuit 30 has a high-pass filter 31 and an integrator 32, performs an operation based on a signal DS indicating the count value outputted from the counter 14, and outputs the signal FS after the operation.
