1. ### help with power electronic

Hi. can anyone help me solving transfer function of: Vo/VI = f(D). from above circuitry, Or the mean values of ic and i2 as function of i0 and D. and dont know what kind of topology it is...if its buck or buck-boost or others. would be great thanks alot
2. ### shape of a transformer - designing a transformer

hi. can anyone please tell me what geometrys can a transformer have: i know it have square or rectangle or toroid... but what im asking if there is more. if so. what is best..toroid?, which has higher efficiency and all that kind of information. thanks in advance
3. ### [SOLVED] Power Electronic need help solving this :( - Ic rms in buck-boost

An ideal buck-boost converter with a switching frequency fsw = 250 kHz is operating with a duty cycle d = 66.667 % and delivers an output power of P = 100.00 W into a purely resistive load. Its input voltage is Vin = 10.00 V and the inductor is L = 6.80 μH. The impedance of the output capacitor...
4. ### [SOLVED] Power Electronic need help solving this :( - I_in_rms value.

dear ppl: i have problem with this problem...ive searched all internet and my books..cant find answer to this or formula... An ideal buck-boost converter with a switching frequency fsw = 200 kHz is operating with a duty cycle d = 33.333 % and delivers an output power of P = 50.00 W into a...
5. ### Help power electronic :(

A time varying voltage v(t) as shown in figure 1 is connected across an inductor L with a value of 200 μH. The inductor current iL at t = 0 is 0.5 A. How much energy is stored at t = 20 μs? given graph: please help asap:|
