摘要
A PWM-FM control method and circuit is employed to control the output level of a resonant switch-mode inverter/converter. The frequency of the inverter/converter is controlled via a nonlinear function shaper and VCO or ICO by the same voltage which controls the pulse-width such that the turn-on of the controlled switching element(s) always occur(s) at substantially zero voltage and substantially zero current across the switching element(s), thereby minimizing switching losses and maximizing efficiency.
