Abstract: The significance of researching on solar photovoltaic -engineering systems is simply introduced theory of
solar photovoltaic -engineering systems main circuit is particularly posed of buck -boost system circuit
based on the TMS320LF2812, software and digital PID controller are particularly designed. The e of experiment and technical
parameter are bidirectional DC -DC converter of digital control realized charging and discharging stability between the
solar panels and batteries .And the charging and discharging fast switching.
Key words: photovoltaic-engineering ;bidirectional DC-DC ;TMS320F2812 ;digital PID
太阳能光伏发电是未来能源利用的一大趋势, 逐渐缺点十分明显, 开关数量多, 控制复杂, 效率相对低下。
