摘要:
根据半导体桥的点火特性和工作特点,基于能量守恒定律,通过分析半导体桥输入能量的近似分布,建立了低于熔化温度的桥体升温模型。通过对所建模型的数值分析,分别得到了在不同的外加电压、散热系数和比热容下的桥体温度升高曲线,以及在不同电压下的输入能量分布曲线。曲线的分布规律表明:在电容一定时,外加电压越大桥体升温越快;能量散失越多,达到桥体熔点的时间越长;比热容越大,桥体温度变化越缓慢,达到熔点的时间越长。这些曲线分布规律验证了模型建立的可行性与合理性。
Abstract:
According to the ignition characteristics and operating features of the semiconductor bridge(SCB) and the law of energy conservation,the approximate distribution of input energy of the SCB is analyzed,and the temperature-rising model of SCB is established before the melting point of bridge.By numerical calculation,the distribution curves of rising temperature are obtained with different input energy,dissipation coefficients and specific heat capacities,and the energy distribution curves with different input voltages are also obtained.The distribution rule of the curves show: when the capacitance value remains constant,the higher the input voltage is,the faster the temperature increases;the more the energy dissipates,the longer the melting point arrives;the greater the heat capacity becomes,the slower the temperature changes,and at the same time the longer the melting point arrives.Compared with the experimental result,the feasibility and the rationality of the model is validated.
