Full shunt boost switching voltage limiter for solar panel array |
摘要 |
According to the present invention a bus voltage limiter is connected between a photovoltaic solar panel array and a load to limit the output voltage to a fixed dc reference voltage. The limiter includes a pulse width modulator which controls the duty cycle of a power switch from 0% to 100% to maintain a substantially constant output voltage Vref. A coupled inductor type boost DC to DC converter includes a pair of main windings which cooperate with the duty cycle modulated power switch to provide the output voltage. An auxiliary winding provides input ripple current cancellation in conjunction with a second inductor and a dc blocking capacitor.
