Step Up/Down Chopper (Buck-Boost Chopper)
A step up/down chopper also known as a buck-boost converter is a power electronics device designed to control and modify the voltage level supplied to a load . This chopper operates by employing pulse width modulation techniques to control average output voltage making it a versatile tool for both increasing and decreasing the DC voltage. It belongs to the family of chopper circuits ,which are used for DC-DC voltage conversion .The primary function of a step-up/down chopper is to either increase or decrease the input DC voltage to achieve the desired output voltage .The basic configuration of a step up/down chopper consists of a semiconductor switch , a freewheeling diode , an inductor and a load .The chopper operates periodically turning the switch on and off at a high frequency . During the on state , energy is stored in an inductor and during the off state this stored energy is transferred to the load through the freewheeling diode.
