The class-E power amplifier is widely used due to its high efficiency, resulting from switching at zero voltage and zero slope of the switch voltage (i.e. ZVS and DZVS). This paper presents an analytical expression of the gain between the DC input voltage and the peak switch voltage on an ideal class-E power amplifier (PA) with finite dc-feed inductance, ZVS and DZVS operation. This expression is...
This paper analyzes the maximal power loss in the output diode of flyback switching converter operating in both continuous conducting mode (CCM) and discontinuous conducting mode (DCM). Comparing with the previous work, this paper extends the condition, under which the maximal power loss of the output diode occurs, from the CCM to the DCM. Three correlative tasks are included. Firstly, through an...
In this paper, the operating principle of a soft-switching three-phase PWM inverter circuit and its experimental result verification are discussed and analyzed firstly. Then a comparative method is employed to obtain the detailed mathematical description of power loss and efficiency for the discussed soft-switching inverter circuit, and presents the power loss simplified models of inverter circuit...
