| description | The invention relates to a switching loss calculation method and device, computer equipment, a computer readable storage medium and a computer program product. The method comprises the following steps: acquiring a collector current waveform curve and a collector-emitter voltage waveform curve of a transistor in each switching period; for each switching period, simplifying the collector current waveform curve in the switching period to obtain a current simplified waveform curve, and simplifying the collector-emitter voltage waveform curve in the switching period to obtain a voltage simplified waveform curve; and calculating the switching loss in the switching period based on the current simplified waveform curve and the voltage simplified waveform curve after time synchronization. By adopting the method, the error of loss calculation can be remarkably reduced.
