| Abstract: | Reserve inverter which used the PIC18F1330 processor as the core controller adopts the inversion mode of AC-DC-AC and produces SPWM running signals for the inversion currency.In the meanwhile the inverter runs such protective functions as voltage stabilization,over-voltage,and under-voltage and temperature protection.The designed reserve inverter is characterized as stable voltage and few aberrations and has been proved to be very practical since it has confirmed the medical ultrasonic diagnostic equipment emergency generator requirements. |
