Design Details

The MC 33063 control chip manufactured by Motorola is used for the switch control.This particular chipas chosen because of minimum number of external components required to implement the design. This device also consists of a 1.25 V reference regulator a component and a controlled duty cycle oscillator. The oscillator charges and discharges an external timing capacitor

Simulation Procedure in Multisim 11.0
A pulse was used to mimic the operation at the control chip.An on time of 9.83 ms and an off time of 6.16 ms were entered into the attributes of the pulse.The circuit was simulated with 150 ohm resistor connected across the output capacitor.

Design Verification
Test Setup

The boost converter was built on a standard bread board. The 5 vdc input voltage was supplied by RC components solar PV cells.. All DC measurements were taken using multimeter and all waveforms were obtained via an oscilloscpe
