npredictab Frequency and militer design is often difficult. 2. TYPES OF CHOPPER: 2.1 FIRST QUADRANT OR TYPE A CHOPPER: V. CH1 1 CHLFD FD 7 No LOAD (b) (a) When switch ON Current i, flows in the same direction when switch off. V.=0, 1,=0 So, average value of both the load and the current are positive. v-4via-var. , If we consider the converter to be loss less then the input power is equal to the output power and is given by 2 Vidt dt 1V (AT) = TR +(at)= av? R The effective input resistance seen by the P source is R *** a The duty cycle a can be varied by varying to, T of frequency. Constant frequency operation: Solve the equation 43x at + + 2x=e given that x(0)=0.x (0)=1
