This paper reviews recent advances and current debates in modeling the solar cycle as a hydromagnetic dynamo process. Emphasis is placed on (relatively) simple dynamo models that are nonetheless detailed enough to be comparable to solar cycle observations. After a brief overview of the dynamo problem and of key observational constraints, I begin by reviewing the various magnetic field regeneration mechanisms that have been proposed in the solar context. I move on to a presentation and critical discussion of extant solar cycle models based on these mechanisms, followed by a discussion of recent magnetohydrodynamical simulations of solar convection generating solar-like large-scale magnetic cycles. I then turn to the origin and consequences of fluctuations in these models and simulations, including amplitude and parity modulation, chaotic behavior, and intermittency. The paper concludes with a discussion of our current state of ignorance regarding various key questions relating to the explanatory framework offered by dynamo models of the solar cycle.

本文回顾了将太阳周期建模为水磁发电机过程的最新进展和当前的争论。重点放在（相对）简单的发电机模型上，尽管如此，这些模型仍然足够详细，可以与太阳周期观测相媲美。在简要概述了发电机问题和关键观测限制之后，我首先回顾了在太阳背景下提出的各种磁场再生机制。接下来，我将对基于这些机制的现有太阳周期模型进行演示和批判性讨论，然后讨论最近对太阳对流产生类似太阳的大规模磁循环的磁流体动力学模拟。然后，我转向这些模型和模拟中波动的起源和后果，包括幅度和奇偶校验调制、混沌行为和间歇性。本文最后讨论了我们目前对与太阳周期发电机模型提供的解释框架相关的各种关键问题的无知状态。
