Power Loss Calculator

Calculate conduction and switching losses in power converters. Evaluate system efficiency.

Input Voltage (V)

Output Voltage (V)

Output Current (A)

MOSFET R_DS(on) (mΩ)

Switching Frequency (kHz)

Rise/Fall Time (ns)

Conduction Loss: P_cond = I² × R_DS(on) × D

Switching Loss: P_sw = 0.5 × V_in × I_out × (t_r+t_f) × f_sw

Efficiency: η = P_out / (P_out + P_loss)
