Abstract In this paper, the design and implementation of complex programmable logic device (CPLD) based solar inverter which generates power of AC 110 volts is proposed. In this framework, the former adopt DC to DC boost convert circuit and the latter adopt bipolar full-bridge inverter, and then complex programmable logic device to control system is used. The system uses four solar photovoltaic modules with connection and then can generate 50∼80 volt of DC. The former DC to DC boost converter voltage and transfers circuit, we adopt pulse-width modulation (PWM) technology and the voltage feedback control to stabilize voltage at the value of 200 volt. The latter converter adopts bipolar sinusoidal pulse width modulation (SPWM) technology such that power cord arrives to 110 volt of alternating current output.
