Abstract: A power-mode controlled power converter is capable of supplying a constant output voltage and output current. A PWM controller generates a PWM signal in response to a voltage sampled from a transformer auxiliary winding. A programmable current-sink and a detection resistor compensate for a voltage drop of an output rectifier. A low-pass filter integrates a switching-current voltage to an average-current signal. An attenuator produces an input-voltage signal from a line-voltage input signal. The PWM controller multiplies the average-current signal with the input-voltage signal to generate a power-control signal. An error-amplifier compares the power-control signal with a power-reference voltage to generate a limit voltage. The limit voltage controls the power delivered from a primary-side circuit to a secondary-side circuit of the power-mode controlled power converter. Since the power-reference voltage varies in proportional to output voltage variations, a constant output current is therefore achieved.

Abstract: The present invention provides a forward power converter with a synchronized rectifying controller. The synchronized rectifying controller has a detection input for detecting the voltage of a secondary winding of a transformer, and thereby accurately measuring the PWM signal. Based on this measurement, the synchronized rectifying controller generates control signals for two secondary-side rectifying MOSFETs. The present invention also introduces a delay time using a timing resistor coupled to the synchronized rectifying controller. This avoids cross-conduction from secondary-side MOSFETs. The present invention also includes an output current-sense mechanism to avoid reverse inductor currents under light-load conditions.

Abstract: The present invention discloses a ZCS discontinuous mode PFC controller having a power saving modulator. The controller turns on through the feedback resistor and the parasitic diode of the controller, thus eliminating the need for a startup resistor. To achieve ZCS, the inductor current is released to zero, while the switching signal is off, before the next switching cycle starts. In order to decrease the switching frequency for light load conditions, an off-time delay is inserted right before the start of every switching cycle. The off-time delay is modulated to be the function of the feedback voltage and supply voltage. When the supply voltage is lower than the limit voltage, the off-time delay will decrease to inhibit the decrease of a switching frequency therefore prevents a low supply voltage. The switching frequency is decreased in accordance with the decrease of the load. Consequently, the switching losses and power consumption for light load and no load conditions are reduced.
