Embodiment Construction

[0058] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0059] The invention discloses a continuous function compensation method improved Ton / Toff circuit architecture method, which uses key component parameters or related system design variables as input variables, and uses continuous functions that meet specific conditions to generate compensation amounts, and the upper and lower thresholds make compensation;

[0060] Circuit architecture principle: introduce a compensation amount θ related to the component parameter x for Δ, and the compensation function θ(x) of the relationship between θ and x meets specific requirements;

[0061] If the relationship between f and x is monotonically increasing, that is, for any x>0, df(x) / dx>0 is true, then the compensation function θ(x) only needs to satisfy the following three conditions in the region of x>0:

[0062] (7) θ(x) is a continuous function, that is, θ(x) can be ...

Abstract

The invention relates to a continuous function compensation method improved Ton / Toff circuit structure method, which uses key component parameters or related system design variables as input variables, uses a continuous function that meets specific conditions to generate compensation, and performs upper and lower limit thresholds. compensate. The principle of circuit architecture: introduce a compensation amount θ related to the component parameter x for Δ, and the compensation function θ(x) of the relationship between θ and x meets specific requirements. This method takes key component parameters or their related system design variables as input variables, and uses continuous functions that meet specific conditions to generate compensation amounts, and the Ton / Tof circuit architecture that compensates the upper and lower limit thresholds can be passed with only a minimal increase in cost. Appropriately sacrificing the ripple characteristics alleviates the above contradiction, and can retain good ripple characteristics when the contradiction is not acute, thereby broadening the scope of application of a product and providing the possibility for a specific optimized design of the solution.

Description

technical field [0001] The invention relates to the technical field of electronic circuits and integrated circuits, in particular to an improved Ton / Toff circuit structure method of continuous function compensation method. Background technique [0002] The working principle of the Ton / Toff circuit architecture is attached figure 1 Shown: There is an equivalence relationship between the target parameter and a certain parameter in the system. By switching the on and off states of the power switch in the system, this parameter in the system can be linearly increased and decreased respectively. In this way, only the The parameter sets a lower threshold VL and an upper threshold VH. When the parameter reaches VL, the switch is switched to the on state, and the parameter starts to rise linearly; when the parameter reaches VH, the switch is switched to the off state, and the parameter starts to decline linearly, so that the cycle , then the average value Va of this parameter is eq...
