基于DSP双闭环控制的单相逆变电源设计与实现

逆变电源spwm调制和闭环控制主要由中断程序 完成。中断程序流程如图5所示。进入中断后，首 先对电压和电流进行采样，将采到的数据进行调 理，计算电压的误差，经过pi调节后作为电流内环 的给定值，然后计算电流的误差值，经过比例调节 后生成spwm信号。

positive or negative output. Some types have variable voltage outputs. A typical 7800 series voltage regulator is used for positive voltages. The 7900 series are negative voltage regulators. These voltage regulators when used with heatsinks can safely produce current values of 1A and greater. The capacitors act as line filtration.

LP2950 - Voltage Regulator - Low Power Low, Dropout

100 mA LP2950, LP2951, NCV2951 The LP2950 and LP2951 are micropower voltage regulators that are specifically designed to maintain proper regulation with an extremely low input−to−output voltage differential. These devices feature a very low quiescent bias current of 75 A and are capable of supplying output currents in excess of 100 mA.
